Breakout rooms troubleshooting guide

Why can't I use breakout rooms in my Teams meeting? 

To see Breakout rooms  Breakout rooms icon  in your meeting controls, you must be a meeting organizer of a scheduled private meeting, a Meet Now meeting, a scheduled channel meeting, or a channel Meet Now meeting. Additionally, you need to join the meeting from a supported Teams client for Windows or macOS. 

Linux, web, iOS, iPadOS, Android (including Chromebook), and VDI clients are currently enabled for breakout room attendees, which means participants joining from these clients can be moved to breakout rooms but cannot manage breakout rooms.  

You will not see Breakout rooms  Breakout rooms icon  in your meeting controls if: 

  • You are not a meeting organizer.

  • The meeting was canceled.

  • The thread where the channel meeting was organized was deleted.

  • The meeting was organized in a private or a shared channel.

  • You joined from an unsupported client.

  • Breakout rooms are disabled by a policy through your admin portal.

Some of the meeting participants were not moved to the right breakout rooms. What should I do? 

Certain types of meeting participants can’t be moved to breakout rooms: 

  • Participants who joined from unsupported devices, like desktop phones/PSTN/CVI.

  • Participants who joined with the Call me back option.

  • Participants that are not currently in the meeting.

  • Participants that are using an older versions of Teams.

Tip: Your main meeting may serve as a breakout room for these participants who cannot be assigned to one.

If you’re the meeting organizer and still having trouble moving participants to breakout rooms, try re-assigning them to the rooms. Learn more about how to do that here

The meeting organizer can also try assigning a participant who failed to join a breakout room by navigating to Breakout rooms  Breakout rooms icon  in the meeting controls, hovering over the participant’s name until More options  More options icon appears next to the participant’s name, and then selecting Ask to join. The participant will then be asked to join a room.

There are a few known limitations with moving participants who have been assigned to an open room: 

  • Participants that are not in the breakout room can’t be moved to another breakout room.

  • Participants that are moved from open to closed room will land in the main meeting.

I see an error message when I try to close all breakout rooms. What should I do? 

Try to right click the room that failed to close and select Close room from the menu options.  

Why didn’t some of my breakout rooms open? 

Empty rooms will not open. Additionally, if you set a timer for your breakout rooms and no one joins a room, that room will not open.  

Why did my breakout room with a timer close before time had elapsed?  

If all participants leave the meeting before the timer is up, the room will close automatically. 

How do I control lobby settings for the main meeting? 

You can control whether meeting participants need to be admitted in the lobby from these settings: Change participant settings for a Teams meeting.  

Does selecting End meeting in the main meeting end or close all active breakout rooms? 

No, selecting End meeting will just close the main meeting. To close breakout rooms, select Close rooms from Breakout rooms  Breakout rooms icon . You'll know rooms have successfully closed when their status changes to Closed. 

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  Breakout rooms icon  in the meeting controls: 

  • If more than 300 participants join a meeting and at some point, the participant count goes below 300, Breakout rooms  Breakout rooms icon 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. 

How do I report issues with breakout rooms? 

Share your feedback on breakout rooms by selecting Help > Give Feedback in Teams. You can also ask questions in Microsoft Answers and the Microsoft Tech Community. To troubleshoot another issue with Microsoft Support, you’ll need to have log files from both the meeting organizer and meeting participant machines handy, which can be exported using these steps.
