Microsoft is planning to no longer support the Windows Mail, Calendar, and People apps later this year. The software giant has been moving existing users of these apps over to the new Outlook for Windows app in recent months, and now it has set an end of support date for the Mail, Calendar, and People apps of December 31st.

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.

Microsoft is notifying its Mail and Calendar app users to switch to free web-based Outlook. Many users have reported noticing pop-ups from the app. Microsoft insists users make the migration by December 31, 2024. After that date, the app will only display emails and calendar entries saved until the scheduled date.

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

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.
