Microsoft will retire the Calendar, People, and Files companion apps from its Microsoft 365 suite on December 16, 2026. These apps were launched a year ago to enhance productivity by providing quick access to information via the Windows 11 taskbar. However, their role has shifted from essential tools to supplementary resources, as users can access the same information through existing Microsoft services. Microsoft recommends alternatives such as Outlook, Teams, Windows Search, File Explorer, SharePoint, OneDrive, Word, Excel, and PowerPoint for users to utilize after the retirement of these apps.

Microsoft will retire the Mobile Plans app in Windows 11 by February 2026 to simplify the process of connecting PCs to mobile data. Users will manage cellular plans through web browsers and the Settings app instead of the app. The Mobile Plans app, which allowed users to discover mobile operators and manage pay-as-you-go plans, is becoming redundant as these tasks can now be done online. Existing eSIM profiles will remain functional, but management will shift to carriers' websites. Notifications about the app's end of support will be sent to users, and it will be removed from the Microsoft Store after February 27, 2026. Cellular carriers are adapting their systems for web-based activations to support this transition.
