How do I start using the breakout rooms in Teams?

By default, meeting participants are moved to their assigned rooms as soon as you open the room, but you can turn off this setting; see Turn off automatic entry to breakout rooms.

• To open all the rooms at the same time, select Start rooms.

• To open a single room, select More options   next to the room and then Open room.
  
  

You can open and close breakout rooms more than once during a meeting.
