Body (from Message Center)

Updated August 3, 2026: This feature was temporarily rolled back, and 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 early September 2026 (previously mid-August) and is expected to complete by end of October 2026 (previously end of September).

[How this affects your organization]

Who is affected

All Microsoft Teams users in Microsoft 365 tenants, including Worldwide, GCC, GCC High, and DoD

What will happen

Users may see up to two new system sections in their Teams chat and channels list:

Muted chats section
- Enabled by default.
- Muted chats that are not in Favorites or user‑created sections automatically move to this section.
- The section appears at the bottom of the chat list.
- Unread chats continue to appear bold.
Meeting chats section
- Disabled by default.
- When enabled by the user, meeting chats that are not in Favorites or user‑created sections automatically move to this section.
- The section appears below the main chats list.
- Unread chats continue to appear bold and contribute to badge counts.
Chats in Favorites or user‑created sections are not moved.
Users can drag and drop these sections to reorder them.
There are no admin controls for these sections.

[What you can do to prepare]

No admin action is required.

You may want to:

Inform users that new chat sections are available and that they can turn them on or off.
Notify helpdesk staff that muted chats may appear in a separate section by default.
Direct users to Settings > Chats and channels to manage these sections.

[Compliance considerations]
