Dear colleagues,

Microsoft has announced an update to Microsoft 365 on Windows 11 that introduces new companion apps designed to simplify everyday work. 

What is changing 

Starting in late 2025, Microsoft began automatically installing new Microsoft 365 companion apps on Windows 11 devices that have Microsoft 365 desktop applications installed. The companion apps include: 

• • People 

• • Files 

• • Calendar 

These apps are integrated with the Windows taskbar and are designed to help users quickly access contacts, documents, and meetings without switching between multiple applications. 

What to expect 

• • The Microsoft 365 companion apps will be installed automatically. 

• • No user action is required for installation. 

• • The apps will appear in the Start menu and may be pinned to the taskbar, depending on local device settings. 

• • On devices where these apps are already installed, there will be no visible change. 

Users can choose to pin or unpin these apps from their taskbar. 

If you have any further questions or concerns, please submit a ticket to the Enterprise Service Centre at (https://uoft.me/m365help). 

Kind regards,
