Microsoft 365 Copilot: Copilot Chat for Teams Chats, Channels, Calling, and Meetings

Originally posted by Microsoft Sep 22, 2025 Uncategorized 0 Comments

Microsoft 365 Copilot Chat is being integrated side-by-side in Teams Chats, Channels, Calling, and Meetings for licensed users on desktop and web. Public preview starts October for chats and calls, December for meetings, with general availability following. Prior Copilot history remains accessible via the More Options menu.

We’re excited to announce that we are making Copilot Chat available as a side-by-side experience in Teams. This will help users access the power of M365 and Web data in addition to current capabilities of Copilot in Chats, Channels, Calling, and Meeting. On Teams desktop (Windows and Mac) and web, users can open Copilot Chat from the Copilot icon located on the top right corner in these surfaces. Copilot Chat will be available in Teams for users with a Microsoft 365 Copilot license.

How this affects your organization:

• Upon completion of the migration, all prior Copilot history will not be migrated into the new Copilot Chat experience. However, you can still access prior history by clicking on the More Options menu (…) located on the top right corner of your conversation window.
