GoKawiilMicrosoft to shut down Calendar, People and Files companion apps by December 2026
Microsoft announced it is retiring its Microsoft 365 companion apps—Calendar, People, and Files—effective December 16, 2026, after which they will stop functioning and lose support. The company is telling IT administrators to uninstall the apps from managed devices before that date. The move comes roughly a year after Microsoft began automatically pushing these taskbar-integrated apps to Windows 11 enterprise devices running Microsoft 365 desktop clients.
