No breakout rooms in Microsoft Teams, or people were left out of them

What you are seeing

You want to split a Microsoft Teams meeting into small groups and there is no **Breakout rooms** button — or the rooms opened and some people stayed behind in the main meeting.

The likely causes, most common first

Work down the list; most people find theirs in the first two.

1. You are not the organiser

1. The button appears only for the meeting’s organiser and for people the organiser named as breakout room managers. Ask the organiser to run the rooms, or to make you a manager.

Microsoft: “You are not a meeting organizer or you were not set as a breakout room manager.” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

2. You are on the web, a phone or Linux

1. Running breakout rooms needs the Teams app for Windows or Mac. People on the web, on a phone, on Linux or dialled in can be put in a room, but cannot set rooms up.

Microsoft: “participants joining from these clients can be moved to breakout rooms but cannot manage breakout rooms” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

3. It is a private or shared channel meeting

1. Teams has no breakout rooms for meetings held in private or shared channels. Schedule it from the calendar, or in a standard channel.

Microsoft: “The meeting was organized in a private or a shared channel.” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

4. You are from another company

1. Somebody outside the organiser’s organisation cannot run the rooms, even as a presenter.

Microsoft: “You are not from the same organization as the meeting organizer.” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

5. Some people cannot be moved

1. People on a free Teams account, on an old version of Teams, or on some meeting-room systems cannot be put in a room. The main meeting can be their room.
2. Somebody who has dropped out cannot be moved either — assign them again when they are back.

Microsoft: “Participants signed into a Microsoft Teams (free) account” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

6. Nobody was in the room

1. A room with nobody assigned to it does not open.

Microsoft: “Empty rooms will not open.” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams

7. The meeting is over a thousand people

1. Breakout rooms work in meetings of up to 1,000 people. Above that the button goes, and it stays gone even if numbers drop again.

Microsoft: “Breakout rooms can be organized for meetings of up to 1,000 participants.” — support.microsoft.com/en-us/teams/meetings/breakout-rooms-troubleshooting-guide-in-microsoft-teams
