Microsoft freezes Microsoft 365 companion apps ahead of 2026 shutdown

Microsoft has stopped updates and automatic installations for the Microsoft 365 Calendar, People, and Files companion apps ahead of their permanent retirement on December 16, 2026. Existing copies may continue running until then, but administrators should now prevent redeployment and begin removing them from managed devices.
