Microsoft explains why Windows 11's new Outlook is better than Mail & Calendar but the reasons aren't convincing enough.

Microsoft is ending support for its Mail and Calendar apps for Windows 11, as it moves to make the new online and free Outlook its only mail option.

If you're still using either of these apps, you'll need to switch to the new Outlook or find alternatives soon.

Microsoft may revive the Windows People app as a web app centered around Outlook.com on Windows 11 for Microsoft 365.

Once the apps reach end of support later this year, Microsoft warns that users who haven’t moved to the new Outlook app “will no longer be able to send and receive email using Windows Mail and Calendar.

Microsoft will discontinue the built-in Mail and Calendar apps in Windows 11 after December 31, 2024, urging users to switch to the web-based Outlook app instead.
