What is the maximum number of meeting participants for breakout rooms?
Breakout rooms can be organized for meetings of up to 300 participants. There are some scenarios that would disable Breakout rooms
-
If more than 300 participants join a meeting and at some point, the participant count goes below 300, Breakout rooms
will still be still disabled in the meeting controls. -
If the meeting organizer starts organizing breakout rooms when there are less than 300 meeting participants, the overall meeting size will be automatically limited, or locked, to 300 people. This means that no more than 300 participants will be able to join the meeting until all breakout rooms have been closed, deleted, and the meeting restarts.
Note: In subsequent occurrences of a meeting that has already been locked at 300 participants, no more attendees can join those future occurrences until breakout rooms have been closed and deleted.
Will breakout rooms expire?
Breakout rooms will expire if they're not opened within the past 60 days (like any other meetings). Expired breakout rooms aren't shown in room list. Organizers aren't able to recover expired breakout rooms, but they can still manage other rooms (if present and not expired). They can also add new breakout rooms (numbering will follow incrementally), or they can recreate all rooms from scratch.
