Updated September 21, 2026: We have updated the timeline. Thank you for your patience.
Introduction
Microsoft Teams is introducing two new system chat sections called Muted chats and Meeting chats. These sections allow users to organize their chat and channels list by grouping muted conversations and meeting chats into dedicated sections that users can turn on or off. The new Meeting chats section will replace the Meeting chats filter, that was previously available at the top of the chat and channel list.
This message is associated with Microsoft 365 Roadmap ID 559605.
When this will happen
- General Availability (Worldwide, GCC, GCC High, DoD): Rollout begins in mid-October 2026 (previously early September) and is expected to complete by mid-November 2026 (previously end of October).
