Microsoft is introducing lightweight taskbar apps for Microsoft 365 on Windows 11, which will automatically launch at startup. The People companion app allows users to access an organizational chart and communicate via Teams or email. The File Search companion app enables quick retrieval of Microsoft 365 files by searching for file names, authors, or keywords, and includes a preview feature. The Calendar app provides an overview of upcoming events and allows users to search for appointments or join meetings. These apps are being rolled out to all business users of Microsoft 365 this month, with automatic installation for those who have Microsoft 365 apps on Windows 11, though IT administrators can prevent this, and users can stop the apps from launching at startup.
