Microsoft will retire the Windows Mail and Calendar applications on Windows 10 and Windows 11 at the end of the year, first auto-migrating users to the new Outlook for Windows app in August.
Initially developed for Windows 10, Windows Mail and Calendar are built-in Windows applications that provide an easy-to-use application for retrieving your email and scheduling events, tasks, and appointments.
Microsoft began alerting consumers and enterprise customers that they are retiring the Windows Mail and Calendar apps in 2024, recommending they start testing the new Outlook app.
Windows users can test the new app by enabling a toggle in the upper right-hand corner of Windows Mail to automatically install the new Outlook app and import your settings from the Mail application.
"At the end of 2024 we will be ending support for the Mail and Calendar apps for Windows. The new Outlook for Windows helps people be more productive and in control of their inbox."
"In late August of 2023, we will also begin a process of auto-migrating Mail & Calendar app users to the new Outlook for Windows with an option to go back if they choose," reads the MC650424 bulletin.
