Teams breakout rooms

Breakout rooms in Microsoft Teams meetings let an organiser split a meeting into smaller sub-meetings, then bring everyone back together. They're how you run workshops, training, and large-group discussions that need both whole-group time and small-group time.

Breakout rooms are one of the organiser tools in meetings best practices and are controlled by meeting policies; for workshops they combine with Whiteboard for hybrid workshops, and for events they give way to webinars.

How breakout rooms work

In an active Teams meeting, the organiser (or designated breakout-rooms managers) opens the breakout panel and:

1. Creates N rooms (named or numbered).
2. Assigns participants automatically (round-robin), manually, or lets participants pick.
3. Opens the rooms — participants are moved to their assigned room as sub-meetings.
4. Sets a timer if desired, with countdown displayed to participants.
5. Joins rooms as the facilitator to check in, answer questions, redirect.
6. Broadcasts a message to all rooms simultaneously.
7. Closes the rooms when ready — everyone returns to the main meeting.

Each breakout room is itself a Teams meeting with its own chat, recording (if enabled separately), whiteboard, and screen sharing. Content created in a breakout — chat messages, whiteboard work — is preserved after the room closes and remains accessible to participants of that room.

Configuration in advance

The organiser can configure breakouts before the meeting starts:

• Number of rooms and naming.
• Pre-assigning participants (useful for known attendee lists).
• Designating co-organisers as breakout managers.
• Auto-assign or manual mode.

Pre-configuration saves time when the meeting starts.

Facilitation patterns

A few that work well:

• Liked/Learned/Lacked retrospective: each room takes one category, then rooms close and groups present back.
• Speed networking: short rounds of small-room conversations.
• Case-study analysis: each room takes a different case, then synthesises in main meeting.
• Training breakouts: hands-on exercises in small groups during a larger training session.

Pair with Microsoft Whiteboard in each breakout for visual collaboration; the whiteboards persist after closing.

Limits and caveats

• Up to 50 breakout rooms in a single meeting.
• External participants can be assigned to breakouts (guests, federated users).
• Anonymous participants can't join breakouts directly — the organiser must make them registered first.
• Recording in breakouts is independent of the main meeting recording.
• Mobile participants can join breakouts on iOS and Android but with reduced facilitator features.

When breakouts are right

• Workshops and training sessions.
• Strategy sessions with parallel work streams.
• Large-group brainstorms where everyone-at-once becomes unwieldy above ~20 people.
• Cohort-based learning programmes.

When they're not

• Casual meetings where the overhead isn't worth it.
• Very short meetings — breakouts take a few minutes to set up and join.
• Town halls and webinars — broadcast formats, not breakout-friendly.

For meeting facilitators running workshops in Teams, breakout rooms are one of the most practical features in the product. The skill is in the facilitation, not the tooling — but the tooling has matured enough not to get in the way.
