Capability-based event labels now replace webinar and town hall names across Teams guides

The period is dominated by a coordinated terminology pass across event administration. Microsoft Learn now uses “Events up to 1k attendees” and “Events optimized for a large audience” in policy references and event guides, while individual pages rename anonymous-attendance, transcription, and event-chat controls. The recording guidance also distinguishes events with up to 1,000 attendees from large-audience events and clarifies policy assignment.

Teams · Policies and settings Policy references adopt audience-size labels

The Settings Policies Reference replaces webinar and town hall terminology with the exact labels “Events up to 1k attendees” and “Events optimized for a large audience” across related settings.

Meetings and events · General Recording guidance separates event audience sizes

The Meeting Recording article now groups webinars and town halls under events, documents recording settings for events with up to 1,000 attendees or for large audiences, and clarifies policy-assignment instructions.

Meetings and events · General Anonymous-attendance steps use the new event labels

The Anonymous Users In Meetings guide now refers to “Who can attend events up to 1k attendees” and “Who can attend events optimized for a large audience,” with corresponding updated configuration steps.

Meetings and events · General Caption controls retain defaults under renamed toggles

Meeting Transcription Captions replaces the webinar and town hall toggle names with attendee-based labels and clarifies policy-assignment steps. Both settings remain On by default.

Meetings and events · General Event chat receives an audience-based setting name

The dropdown label “Town hall chat experience” is now “Events optimized for a large audience chat experience.” Its options remain Optimized (default) and None.

Teams Rooms app update tool is no longer recommended for new Autopilot deployments

This was a quiet, documentation-led day with one actionable Teams Rooms change. The Autopilot guidance says the Teams Rooms app has included automatic updates since April 2024, so the app update tool is no longer recommended for new deployments. A separate known-issues entry records possible Large Gallery unavailability on specified Teams Rooms for Android versions, while release notes document a low-bitrate video fix. Teams Phone updates only reorder language entries in reference and setup material.

Teams Rooms · General Autopilot guidance changes the app update tool recommendation

Because the Teams Rooms app has included automatic updates since April 2024, the app update tool is no longer recommended for new deployments. Administrators should review Intune configurations and consider unassigning the tool, except when deploying devices older than 2025.

Teams will organize muted and meeting chats into dedicated sections in January

Microsoft Teams will introduce a January 2027 chat reorganization: the Muted chats section will be enabled by default, while Meeting chats will be disabled by default, with users able to toggle and reorder both. Two worldwide changes are also planned for December 2026: a Workflows template that links team tags to channel membership and mobile call declines with chat messages. Documentation updates add certified-device entries and SlimCore troubleshooting detail.
