Additional meeting and call-related features and issues within Microsoft Teams for business
Hi Andrew,
To set up breakout rooms in advance of a webinar in Teams, you need to:
- Start the meeting or open the meeting invite.
- In the meeting controls, select Breakout rooms.
- Select the number of rooms you want (up to 50) and whether you want Teams to assign people to rooms automatically or manually.
- Select Create rooms and assign participants if needed.
- Start the breakout rooms when you are ready.
