Windows 11’s Calendar and Mail Apps: Unpredictable Functionality Raises Concerns


January 3, 2025 by our News Team

Microsoft has discontinued support for the native calendar and email apps on Windows 11, urging users to switch to the new Outlook app before the old apps' functionalities deteriorate.

  • Official support for the native calendar and email app on Windows 11 has been discontinued.
  • Microsoft will no longer provide updates or support for the app's functionalities.
  • The new Outlook app is currently the best alternative for those seeking a quick replacement for the native email client on Windows 11.


As we enter 2025, some changes are in store for the native apps on Windows 11, specifically the calendar and email applications. Microsoft had already confirmed that support for these apps would be discontinued, and now that moment has arrived.

Since December 31, 2024, the native calendar and email app on Windows 11 has been without official support. With this move, Microsoft will no longer be providing updates or support for the app’s functionalities. While the app may still continue to work properly on existing systems, there is a possibility that some features or the entire application may stop functioning.

It has been over six months since Microsoft started warning users about the discontinuation of the native email app on Windows 11, while simultaneously encouraging them to switch to the new Outlook app. During this time, Microsoft has also been urging users to migrate their content to the new app. While the old email app is still accessible for those who have it installed, its functionalities are likely to start deteriorating. Therefore, it is highly recommended to make the migration as soon as possible if you still rely on it for your day-to-day email needs.

Although the new Outlook app has its own set of issues, such as the lack of offline support, it currently stands as the best alternative for those seeking a quick replacement for the native email client on Windows 11.
