Microsoft is shutting down the built-in Mail and Calendar apps in Windows 11, which means you’ll no longer be able to send or receive emails or manage your calendar using those apps after December 31, 2024. Microsoft has been using pop-up notifications about this in both apps for months – and the end is in sight.
To use those apps after December 31, switch off the ‘New Outlook’ setting by unchecking it in the new Outlook app’s settings, Outlook > Settings > General > About Outlook.
It s likely to be a ‘view-only’ mode, for emails, drafts, contacts, and other details in the Mail and Calendar apps, but not o send or receive emails, for which you will be redirected to the web-based Outlook. It apparently doesn’t work offline yet, and Microsoft is working on adding support for this in the next few weeks,
