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.

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.
