Body (from Message Center)

Updated August 26, 2026: We have updated the timeline. Thank you for your patience.

[What and why]

Users will now be able to control their channel notification settings using three presets: All new messages, Mentions and replies, and Mute. Users can further customize the selected preset to manage notifications for unfollowed threads, tag mentions, channel mentions, and team mentions within each channel, as well as control banner notifications for the channel

This gives users more control over what is important in each channel, leading to an improved triaging experience and reduced noise.

This message is associated with Microsoft 365 Roadmap ID 565132.
