Windows Live Mail
DeveloperMicrosoft
Final release2012 (v16.4.3528.0331) (November 4, 2014; 11 years ago (2014-11-04)) [±]
Operating systemWindows 7, Windows Server 2008 R2, Windows 8[1]
Type
LicenseFreeware

Windows Live Mail (formerly named Windows Live Mail Desktop, code-named Elroy[2]) is a discontinued freeware email client from Microsoft. It was the successor to Windows Mail in Windows Vista, which was the successor to Outlook Express in Windows XP and Windows 98. Windows Live Mail is designed to run on Windows 7 and Windows Server 2008 R2, but is also compatible with Windows 8[1] and Windows 10, even though Microsoft bundles a new email client, named Windows Mail, with the latter.[3] In addition to email, Windows Live Mail also features a calendar, an RSS feed reader, and a Usenet newsreader.

Windows Live Mail moved away from the older Microsoft mail programs, such as Outlook Express, which stored all e-mails comprising a folder (such as the Inbox) in a single .dbx file. In order to provide greater flexibility (and to avoid the problem where corruption of a single .dbx file could delete multiple emails), Windows Live Mail stores each email message as a separate .eml file. Only the folder structure is maintained in a single database file, using the ESE (Extensible Storage Engine) database structure, named Mail.MSMessageStore (which also holds some metadata for each .eml file on the system, so can be a huge file). The program also maintains a backup copy of that file, in the Backup sub-folder, so problems are rare. At a pinch, the Mail.MSMessageStore file can be recreated from the data in the .eml files.[citation needed]

History

[edit]

Version 12 (Wave 2)

[edit]

The first version of Windows Live Mail was released on 6 November 2007. The Windows Live Mail version numbering starts at 12 because this application is an advancement of Windows Vista’s Mail program, not an entirely new application. Windows Live Mail is developed by the same team that wrote Windows Mail (Vista).

Despite this, Windows Live Mail was never pre-installed with Windows Vista and instead provided a download link to Windows Live Essentials in Windows Vista’s Welcome Center, a trend that continued with Windows 7.

Windows Live Mail has all of the features of Windows Mail (Vista). It also adds the following new features:

  • Support for Web-based email accounts including Hotmail, Gmail, and Yahoo! Mail Plus.
  • A different user interface which matches the other Windows Live "Wave 2" applications.
  • Synchronization with Windows Live Contacts.
  • Support for RSS feeds. Notable features include the ability to reply directly via email to the author of an item that appears in an RSS feed, and the ability to aggregate multiple feeds into a single folder. The RSS functionality requires Internet Explorer 7 or newer and syncs with the Common Feed List (CFL) on Windows.
  • Multi-line message lists.
  • Emoticons based on Windows Live Messenger’s designs can be used in emails and other functions.
  • In-line spell checking.
  • Separate inbox folders for different POP accounts.
  • Support for sending picture files in emails through the Photo email feature, which uploads pictures to a web-based service and sends the URL and thumbnails in the mail. It can also perform basic photo correction and apply different border effects to pictures.
  • Theme color customization via the brush icon on the command bar with a default color, 12 preset colors, and the color set in Windows Vista and newer.

Comparison with Windows Mail

[edit]

While Windows Live Mail is the successor to Windows Mail (Vista) on Windows Vista, there were several differences in functionality between Windows Live Mail and Windows Mail when it was released in 2007. These include:

  • Ability to view and edit HTML email by source has been removed in Windows Live Mail
  • Ability to set margins has been removed
  • Scripted Stationery for Windows Live Mail 2011 is available from Cloudeight Stationery
  • Locally installed help documentation is not available for Windows Live Mail
  • Support for using different mailboxes with separate folders (inbox, junk and so on) was added in Windows Live Mail
  • Support for DeltaSync, a proprietary protocol for access to Windows Live Hotmail email accounts, was added in Windows Live Mail
  • Support for WebDAV, a HTTP-based protocol (web-based email accounts), developed for Outlook Express, was added in Windows Live Mail
  • Ability to perform a full-text index-based search in Windows Live Mail if Windows Search is installed

Version 2009 (Wave 3)

[edit]

A beta version of Windows Live Mail was released in September 2008. It featured a new user interface based on Windows 7 which, like the other Windows Live "Wave 3" beta applications released at the same time, has no icons on the toolbar buttons, like Windows 7. It also features a new calendaring function; calendar events automatically synchronize between Windows Live Mail and the Web-based Windows Live Calendar. A "beta refresh" version of Windows Live Mail was released on 15 December 2008, and this version was officially released as the final version on 8 January 2009. This was the last version to support Windows XP.[4]

Since Windows 7 did not come with a pre-installed email client, it had to be installed separately. Windows Live Mail was the only supported email client alongside Microsoft Outlook to have been supported by Microsoft at the time until the Windows 8 Mail app released.

Version 2009 still contains the same MIME problem with signed mail[5] that Outlook Express has.

Version 2011 (Wave 4)

[edit]

The first beta became available on 24 June 2010, sporting ribbons in the user interface and a calendar pane. The second beta came with a new start-up screen and other minor updates. The final version of Windows Live Mail 2011 was released on 30 September 2010, along with the Windows Live Essentials 2011 suite. It requires Windows Vista or newer; Windows XP is no longer supported.[4]

Version 2012 (Wave 5)

[edit]

On 7 August 2012, Microsoft released a new version of Windows Essentials 2012, which included Windows Live Mail 2012. It requires Windows 7, Windows Server 2008 R2, Windows 8,[1] or Windows 10.[3] Windows Vista is no longer supported.[4]

There are no significant differences from Windows Live Mail 2011, save the discontinuance of support for Vista and DeltaSync. The only technical difference is the replacement in Windows Live Mail 2012 of DeltaSync by Exchange ActiveSync. User forums report significant problems with the upgrade software, KB3093594, so it is recommended not to attempt to upgrade from Windows Live Mail 2011,[6][7] and there are no benefits in doing so, as both versions are identical, unless the user wishes to use Exchange ActiveSync. But by switching from Deltasync to IMAP, Windows Live Mail 2011 continues to work, without needing either Windows Live Mail 2012 or the upgrade.[8]

Issues reported

[edit]

Since around 2013, serious problems with Windows Live Mail 2012 (but not with Windows Live Mail 2011) have been reported on various blog sites (including Microsoft forums). One problem is that deleted emails keep returning day after day.[9] Another development that caused complaints is the Live Mail Sent folder erroneously containing the name of the Sender rather than the Recipient in the To column, while omitting the sender's account name in the Account column (as the fault only affects that folder, a workaround is to move sent items into a new folder, named - for example - "Sent 2019").[10] Discussions on the forums have provided no clear solutions to these issues.

Replacement

[edit]

Microsoft announced that Outlook.com was discontinuing support for Windows Live Mail during 2016[11] by discontinuing use of the DeltaSync protocol. Microsoft has positioned the Mail app (bundled with Windows 10, available in the Microsoft Store) as a replacement for it.

Although use of DeltaSync has been discontinued on Microsoft's servers since 30 June 2016, Windows Live Mail 2011 and 2012 continue to work with Hotmail e-mail accounts by using IMAP (or, less effectively, POP3) instead of DeltaSync.[12][13] Gmail and other service providers still support DeltaSync,[14] so users can still use Windows Live Mail 2011 - connecting with DeltaSync - with non-Microsoft email accounts (but not Windows Live Mail 2012, as DeltaSync support was removed from it). Additionally, Windows Live Mail 2011 and 2012 continue to function with all non-Microsoft e-mail services, by using IMAP (or, less effectively, POP3) instead of DeltaSync.[15]

Windows Essentials 2012, including Windows Live Mail 2012, reached end of support on 10 January 2017, and is no longer available for download from Microsoft;[16] but most of the software bundled in it or in Windows Essentials 2011, including Windows Live Mail, continues to function[17] and it can still be downloaded from Archive.org.[18][19] The 2011 version is also still available.[20]

from Grokipedia
Windows Live Mail was a free desktop email and newsgroups client developed by as part of the Essentials suite of applications. Introduced in 2007 as the successor to (from ) and Windows Mail (from ), it provided users with a standalone solution for managing email accounts outside of web-based services. The application featured an updated with support for Windows Vista's Aero visual style, streamlined setup and account migration processes, and enhanced performance and stability compared to its predecessors. A key capability of Windows Live Mail was its synchronization of emails and contacts with Windows Live Hotmail accounts via Microsoft's proprietary DeltaSync protocol, delivering an experience akin to Microsoft Exchange Server without requiring a subscription. It supported standard email protocols such as POP3, IMAP, and HTTP for connecting to various providers, along with S/MIME encryption and LDAP directory services for secure and enterprise-like functionality. Later iterations, including the 2012 version, integrated additional tools like a calendar for scheduling and event management, an RSS feed reader for subscribing to web content updates, and support for Usenet newsgroups. The software reached its final release as Windows Live Mail 2012 within the Windows Essentials 2012 package, which was made available until early 2017. Microsoft ended support for the entire Windows Essentials suite on January 10, 2017, after which downloads were discontinued and no further updates or security patches were provided, though existing installations could still operate. Prior to this, in mid-2016, Microsoft blocked connections from Windows Live Mail 2012 to its email services—including Outlook.com, Hotmail, and MSN Mail—due to a shift toward modern authentication methods and API updates in the Outlook.com backend, rendering the client incompatible with Microsoft-hosted accounts. As a result, users were encouraged to migrate to alternatives such as the built-in Mail and Calendar apps in Windows 10 or the full-featured Microsoft Outlook application.

Background and Development

Predecessors

Outlook Express served as the original free email client developed by Microsoft, bundled with Internet Explorer versions 3.0 through 6.0 and included in operating systems from Windows 95 through Windows XP. It originated as Microsoft Internet Mail and News in 1996, providing basic support for POP3 email and NNTP newsgroups. However, due to persistent security vulnerabilities, including risks of remote code execution from malformed messages, Microsoft discontinued further development and production of Outlook Express after the release of Windows XP Service Pack 2 in 2004, with support ending alongside Windows XP SP3 in April 2014. Windows Mail emerged as the direct successor to , debuting in 2007 with the release of as version 7.0. It incorporated improvements to address some of Outlook Express's shortcomings, such as enhanced junk email filtering through periodic definition updates and basic detection. Nonetheless, Windows Mail was exclusively available on , receiving no major feature updates beyond initial security patches tied to the operating system's lifecycle, which concluded mainstream support in 2010 and extended support in 2017. In response to user demands for broader compatibility across operating systems like and , as well as the need for ongoing enhancements, transitioned to a downloadable model with the Essentials suite, first introduced in beta form in 2007. This shift enabled the —later known as Windows Live Mail—to receive regular updates independent of OS releases, supporting cross-platform use while evolving from the OS-integrated predecessors. Key drivers for this evolution included the imperative to bolster defenses against spam and attacks, which had plagued earlier clients through unpatched vulnerabilities and inadequate filtering. aimed to integrate advanced protections like SmartScreen filtering, drawing from data in Windows Live Hotmail to improve threat detection in desktop applications. Additionally, seamless connectivity with web-based services such as Hotmail was prioritized to unify user experiences across desktop and online environments. Windows Live Mail represented the next iteration in this lineage of Microsoft's free email clients.

Initial Release and Purpose

Windows Live Mail was initially released on November 6, 2007, as Version 12 (Wave 2) within the Essentials suite, a free downloadable bundle of applications designed to replace previously bundled software in the operating system. The primary purpose of Windows Live Mail was to serve as a modern, standalone for Windows users on systems beyond , focusing on seamless integration with 's online services such as Hotmail and Windows Live Messenger to bridge desktop and web-based communication. This integration allowed users to synchronize emails and contacts effortlessly, providing an experience akin to Microsoft Exchange for consumer accounts without requiring enterprise-level infrastructure. In its development context, Windows Live Mail emerged as part of Microsoft's broader "" wave strategy initiated in , aimed at unifying desktop applications with web services to deliver a cohesive of free tools. Initial beta testing began in May 2007, building on the foundations of earlier clients to address user demands for enhanced , faster setup, and cross-platform accessibility. At its core, the software adhered to a freeware model with optional installation, emphasizing ease-of-use for non-enterprise users as a lightweight alternative to the full application. This approach enabled broad adoption among home and small-scale users seeking a simple yet capable email solution without subscription costs or complex configurations.

Features

Email Functionality

Windows Live Mail served as a desktop email client capable of managing multiple email accounts through support for POP3, which downloads messages to the local computer; IMAP, enabling synchronization across devices; NNTP for accessing newsgroups; and HTTP protocols, particularly for accessing web-based services like Hotmail and . This multi-protocol compatibility allowed users to consolidate emails from diverse providers into a single interface, facilitating centralized management without relying solely on web browsers. The emphasized efficient organization, featuring threaded conversations that grouped related messages under a single expandable entry, marked by a triangular for easy through reply chains. Quick Views provided predefined filters at the top of the folder pane, such as displays for unread messages or high-priority items, streamlining access to specific subsets of emails without altering the underlying folder structure. Message rules enabled automated processing, where users could define conditions to filter, flag, delete, or forward incoming emails based on criteria like or subject, enhancing inbox control. Advanced search functionality supported indexing for rapid queries across content, attachments, and metadata, with options to create custom views as dynamic, self-updating folders tailored to user-defined parameters. Attachment handling integrated seamlessly with the Windows environment, permitting drag-and-drop insertion of files directly into the compose window from the desktop or Explorer. Users could preview attachments by double-clicking their icons within received messages, supporting quick review without full downloads, and extract files by dragging them to Windows Explorer locations like the desktop for local storage. Security measures included a built-in filter that scanned incoming messages for fraudulent links or sender deceptions mimicking trusted sources, alerting users to potential risks. Junk mail controls routed suspected spam to a dedicated Junk E-mail folder, with configurable levels from low to high scrutiny, allowing manual overrides to the filter over time. Support for digitally signed messages was available through the Security tab in composition options, enabling users to apply digital IDs for and to verify message integrity and origin. Additionally, it offered brief integration with and contacts for unified management, such as converting email content into appointments or addressing messages from synced contact lists.

Additional Integrated Tools

Windows Live Mail integrated a feature that allowed users to manage appointments, events, and reminders directly within the application, syncing seamlessly with the online Windows Live service. This integration enabled the creation of multiple calendars, import of (.ics) files, and two-way synchronization of entries when signed in with a Windows Live ID, ensuring that changes made in the desktop client reflected online and vice versa. Users could receive desktop reminders for appointments, facilitating shared calendars for collaborative scheduling without leaving the interface. The contacts management system in Windows Live Mail provided a unified address book that supported detailed entries including personal information, work details, notes, and digital IDs for secure communications. It integrated photos from Windows Live services, automatically pulling profile images associated with contacts' Microsoft accounts to enhance visual recognition in the interface. Synchronization with Windows Live Contacts allowed for automatic updates of address changes and displayed real-time online status indicators (such as green for available or red for busy) for users connected via Windows Live Messenger, with options to import and export contacts in standard formats like CSV or vCard for portability across devices. Windows Live Mail included a built-in RSS feed reader that functioned as an aggregator for subscribing to web feeds in or Atom formats, displaying them alongside in the folder pane for unified access. Users could organize feeds into subfolders for categorization, with unread items highlighted in bold and previews available in the reading pane, including embedded images for quick content scanning without opening external browsers. Subscription was straightforward via a dedicated Feeds , allowing integration of , blogs, and updates directly into the productivity workflow.

Version History

Version 12 (2007)

Windows Live Mail version 12.0, released on November 6, 2007, marked the debut of Microsoft's free desktop email client as part of the Wave 2 suite of services and software. This initial release focused on extending email capabilities beyond the built-in Windows Mail application in , particularly by addressing key limitations such as the absence of feed integration and calendar functionality. The software was made available for download worldwide, supporting both and operating systems, and served as a successor to for older systems while providing standalone installation independent of the operating system bundle. A core innovation in version 12.0 was its enhanced support for HTTP-based access to Hotmail accounts, enabling seamless management of web-based alongside traditional POP3 and IMAP protocols for other providers like and . This allowed users to aggregate multiple inboxes into a unified view, consolidate contact lists across accounts, and access emails from mobile devices through integration with services. The client retained the foundational engine from Windows Mail but expanded functionality with built-in tools for handling attachments more efficiently, including drag-and-drop support and virus scanning during downloads. User interface improvements included a cleaner layout with options for reading panes and quick filters, though it did not introduce full tabbed windows until later iterations. In comparison to Windows Mail, which was limited to Vista users and lacked advanced web service ties, version 12.0 offered broader compatibility and deeper ecosystem integration, such as one-click access to Windows Live Messenger and Spaces for sharing content directly from emails. It introduced an RSS feed reader leveraging the Windows RSS Platform, permitting users to subscribe to and manage up to hundreds of feeds synced with 7's Common Feed List, including features like unread item search folders and customizable update intervals. Additionally, it incorporated a basic calendar component for local event management and reminders, resolving Windows Mail's separation of email from scheduling tools, though full online synchronization with Calendar arrived in subsequent updates. Security enhancements included improved phishing detection and attachment scanning, building on Vista's capabilities with Live-specific protections for Hotmail traffic. The release was well-received for its free availability and accessibility, quickly gaining traction among users seeking a modern alternative to bundled OS tools, with the broader suite seeing widespread adoption in its first year.

Versions 2009 to 2012

Windows Live Mail saw iterative updates from 2009 to 2012 as part of Microsoft's Windows Live Essentials suite, building on the foundation established in Version 12 by refining user interface elements, integration capabilities, and compatibility with emerging operating systems. These releases, known as Waves 3 through 5, emphasized incremental improvements in and rather than groundbreaking changes, aligning the desktop client more closely with Microsoft's evolving services like Hotmail, which later rebranded to . Version 2009, designated as Wave 3 and released on January 8, 2009 with build 14.0.8117.0416, introduced enhanced support for feeds and an integrated alongside management, allowing users to handle multiple content types within a single application. This version also improved overall interface simplicity compared to predecessors, facilitating easier access to accounts from various providers through an "Add an e-mail account" wizard. While initial compatibility focused on and XP, subsequent updates in 2009 extended support to upon its release, ensuring seamless operation on the new OS without requiring major reinstallations. In 2010, Version 2011 (Wave 4) arrived on September 30, 2010 with build 15.4, marking a significant visual and functional shift by adopting a ribbon-style interface similar to applications, which centralized commands for composing, searching, and managing messages. Conversation view was refined to group related emails into threaded displays, reducing clutter and improving navigation through ongoing discussions, while Quick Views enabled filtered displays of specific message types like unread items or flagged content. Enhanced calendar sharing features allowed better synchronization and collaboration with online services, further bridging desktop and web-based experiences. These updates were distributed via Microsoft's web installer, supporting through 7. The final major iteration, Version 2012 (Wave 5), released on August 7, 2012 under build 16.4.3505.0912, prioritized performance tweaks and broader OS compatibility, including native support for to align with the Metro interface era. Optimizations focused on faster loading of message lists and reduced resource usage during sync operations, addressing user feedback on lag in prior versions. Security enhancements were incorporated through ongoing patches, maintaining compatibility with protocols like POP3, IMAP, and HTTP for cloud-based accounts such as . This release represented the culmination of the suite's development, with no further waves planned, emphasizing polish in cloud syncing for contacts, calendars, and emails. Throughout these versions, a clear trend emerged toward deeper integration, with each wave enhancing connectivity to 's online ecosystem—such as seamless Hotmail/ access and social network syncing—preparing users for a hybrid desktop-web workflow without overhauling core functionalities.

Discontinuation and Impact

End of Support

initiated the phased retirement of Windows Live Mail by discontinuing support for its proprietary DeltaSync protocol, which enabled with Hotmail and accounts, on June 30, 2016. This change prevented seamless integration with 's services, requiring users to reconfigure accounts using standard IMAP or POP3 protocols for basic access, though calendar and contacts syncing ceased entirely. Full support for the Windows Essentials 2012 suite, including Windows Live Mail 2012, ended on January 10, 2017, after which Microsoft ceased providing downloads, new features, or security updates for the application. In official communications starting in 2016, Microsoft urged users to transition to the web-based Outlook.com interface or the built-in Mail app in Windows 10 for continued access to their accounts. Following the end of support, Microsoft servers began restricting connections from unsupported legacy clients like Windows Live Mail to Outlook.com and Hotmail, further limiting functionality. The discontinuation aligned with Microsoft's broader shift toward a cloud-first , emphasizing services like Office 365 and the modern Outlook application, which incorporate advanced security features such as OAuth2 authentication that Windows Live Mail lacked. The legacy software's reliance on outdated protocols posed increasing security risks, and maintaining desktop-based email clients became a low priority amid growing focus on web and mobile experiences. As of November 2025, Windows Live Mail remains incompatible with modern authentication requirements for major providers like , which require OAuth 2.0 and do not support basic authentication for IMAP or POP3. For , however, it can still connect using app passwords generated for accounts with two-factor authentication enabled, despite Google's deprecation of the "less secure apps" option on May 30, 2022. While the application can still operate on legacy Windows systems for local storage and retrieval from compatible servers, it is highly vulnerable to exploits due to the absence of patches or updates since 2017. now recommends alternatives like the web-based or the New Outlook app for Windows as replacements for basic needs, following the discontinuation of the built-in Mail app on December 31, 2024.

Reported Issues and User Migration

Throughout its lifecycle, Windows Live Mail encountered several user-reported issues, particularly in synchronization and compatibility. Sync failures became prominent after Microsoft's 2016 changes to Hotmail and Outlook.com servers, where users experienced Error 3219, preventing connections to retrieve emails due to outdated authentication protocols. Installation errors were common on Windows 10 and later versions, often triggered by system updates that caused the application to fail loading messages or crash entirely, with repair utilities sometimes insufficient to resolve the problems. Additionally, the software's vulnerability to malware increased post-2016 due to the absence of security updates, exposing users to risks like viruses and unauthorized access when handling email attachments or links. Specific bugs in the 2012 version included calendar synchronization lags and crashes, often linked to updates like KB3093594, which halted email syncing for Microsoft accounts unless calendar features were disabled. User reception of Windows Live Mail was generally positive during its active years from 2007 to 2012, praised for its straightforward interface and ease of use compared to predecessors like , making it accessible for non-technical users managing multiple email accounts. However, frustration intensified after discontinuation, as users faced persistent data export challenges, including processes that halted midway or failed to preserve folder structures and attachments during transfers. Migration from Windows Live Mail typically involved exporting data to standard formats like .eml for individual messages or .pst for full archives, allowing into clients such as via built-in tools under File > Open & Export > . provided guidance for transferring emails and contacts to Outlook or webmail services like by first exporting to .eml files and then using the web interface's feature or IMAP reconfiguration. Community workarounds have extended usability into 2025 through third-party tools and manual configurations that bridge IMAP connections to supported servers like (using app passwords), enabling partial syncing despite authentication changes, though these required app-specific passwords and were not officially supported. As of November 2025, some users continue running Windows Live Mail offline on legacy hardware for local access, relying on stored .eml files without internet connectivity. However, experts advise against this due to inherent security risks from unpatched vulnerabilities, which could compromise if the system connects online or processes external files.

Technical Details

Windows Live Mail was officially supported on (all editions), /8.1 (32-bit and 64-bit editions), and , with unofficial compatibility extended to later versions such as until its discontinuation. It requires the installation of .NET Framework 3.5 to function properly, as this provides essential runtime components for its operations. Additionally, or a later version is needed for certain web-integrated features, such as handling content and links within emails. The minimum hardware specifications include a processor with a clock speed of 1.6 GHz or higher, 1 GB of RAM, at least 200 MB of free disk space for installation, and an SVGA-compatible display supporting a minimum resolution of 1024 × 576 pixels. While not officially supported beyond its target operating systems, Windows Live Mail can run on Windows 8, 8.1, and 10 through compatibility mode tweaks, such as running the executable in Windows 7 mode, though users may encounter stability issues or require manual adjustments. On Windows 11, it frequently crashes without the use of virtualization tools like a virtual machine, and it lacks native support for ARM-based processors. As part of the Windows Live Essentials suite, Windows Live Mail is selected as an optional component during the installer's setup process, allowing users to choose only the email client without other tools. The final version, 2012 (build 16.4.3528.0331), received its last security and compatibility update in April 2014, after which no further official patches were issued, even for Windows 10 installations.

Supported Protocols and Compatibility

Windows Live Mail supported standard email protocols including POP3 with SSL encryption for downloading messages and IMAP4 for server-based access, though IMAP implementation required manual configuration of special folders like Sent and Trash for synchronization, resulting in partial folder sync capabilities. It also utilized HTTP and HTTPS for webmail integration, particularly with Hotmail accounts via the proprietary DeltaSync protocol, which enabled seamless synchronization without standard POP or IMAP. A key limitation was the absence of native support for OAuth2 authentication, relying instead on basic authentication methods that became obsolete with modern security requirements. Additionally, Windows Live Mail lacked compatibility with TLS 1.3, restricting secure connections to older TLS versions and exposing vulnerabilities in contemporary network environments. The DeltaSync protocol, specific to Live services for Hotmail and later , was fully deprecated in 2016 as part of infrastructure upgrades to more secure protocols. For service compatibility, Windows Live Mail offered native integration with and Hotmail accounts until June 30, 2016, after which synchronization ceased due to the DeltaSync retirement. Third-party providers like were accessible primarily via POP3, with IMAP support available but limited by the lack of push notifications and requiring app-specific passwords for accounts enforcing two-factor authentication (2FA). Yahoo Mail integration via HTTP/ and POP was supported until 2013, when free accounts lost POP access, shifting to paid or IMAP options with similar authentication hurdles. RSS feeds could be imported using files, allowing subscription management alongside email. As of March 2025, Windows Live Mail is fully incompatible with due to Google's requirement for in third-party apps, and it cannot connect to accounts without modern support.
