Microsoft Teams Breakout Rooms in 2026: Run Engaging Small-Group Sessions at Scale

Large virtual meetings have a problem: most people do not talk. Whether it is a training session for fifty employees, a workshop with thirty stakeholders, or a team all-hands, the bigger the meeting, the fewer voices you actually hear. Breakout Rooms are the solution.

Microsoft Teams Breakout Rooms let you split a large meeting into smaller, parallel sub-meetings — each with their own audio, video, and chat. Participants collaborate in small groups, then return to the main meeting to share findings. In 2026, Teams has expanded Breakout Room capabilities significantly, with Copilot integration, better management tools, and smoother participant experiences.

What Breakout Rooms Are Best For

Breakout Rooms work best when you want active participation rather than passive listening. Common scenarios include:

Training sessions: Divide participants into groups for hands-on exercises or case studies

Workshops and brainstorming: Small groups ideate simultaneously, then report back

All-hands meetings: Break into department groups for Q&A before returning to the main session

Onboarding programs: New hires connect in small cohorts before joining the full group

Town halls: Small group discussions give more people a voice

Education and e-learning: Student groups work on problems together

Setting Up Breakout Rooms: Step by Step

Only meeting organizers can create and manage Breakout Rooms. Here is the full setup process:

Before the Meeting: Pre-Assign Participants

When scheduling the meeting, click the Breakout Rooms option in the Teams meeting scheduling form.

Set the number of rooms you want (Teams supports up to 50 rooms per meeting).

Choose Automatically assign to let Teams divide participants evenly, or Manually assign to control exactly who goes where.

For manual assignment, drag participant names from the Unassigned list into specific rooms.

Save your assignments. Participants will be pre-assigned when they join the meeting.

During the Meeting: Opening Breakout Rooms

Once the meeting is live and participants have joined, click the Breakout Rooms icon in the meeting toolbar (it looks like overlapping rectangles).

The Breakout Rooms panel opens on the right side of the screen.

If needed, adjust room assignments by dragging names between rooms.

Click Open All Rooms to send everyone to their assigned breakout rooms simultaneously.

Participants will see a notification: "The organizer has moved you to a breakout room." They click Join to enter their room.

Managing Rooms While They Are Open

Once Breakout Rooms are open, the organizer stays in the main meeting but has full control over all rooms:

Join any room: Click the three dots next to a room name in the panel and select Join Room to drop in and observe or participate.

Send announcements: Click Make an Announcement to send a text message to all rooms simultaneously. Use this to give time warnings ("5 minutes left") or share new instructions.

Move participants: Drag a participant to a different room at any time, even while rooms are open.

Add rooms: Click Add Room to create additional breakout rooms during the session.

Monitor activity: The panel shows which rooms have active conversations based on audio indicators.

Closing Rooms and Reconvening

When group work is complete, bring everyone back to the main meeting:

In the Breakout Rooms panel, click Close All Rooms.

Teams will send a 60-second countdown to all breakout participants (the default timer is configurable).

When time expires, all participants are automatically moved back to the main meeting.

You can also set a timer in advance: click the settings gear in the Breakout Rooms panel and set an automatic time limit for the session.

Copilot in Breakout Rooms in 2026

One of the biggest improvements to Breakout Rooms in 2026 is Copilot integration. Microsoft Copilot can now:

Summarize each breakout room session independently when the rooms close

Compile a combined summary of all room discussions for the main meeting organizer

Identify common themes and key decisions across all breakout groups

Generate action items from each room based on the conversation transcript

To enable Copilot summaries for Breakout Rooms, make sure meeting transcription is turned on before opening the rooms. After rooms close, look for the Copilot recap in the meeting chat or the Intelligent Recap tab in your Teams meeting history.

Participant Experience and Best Practices

Understanding the participant experience helps you design better sessions:

Participants can chat within their breakout room — the chat is separate from the main meeting chat.

Each room has full screen sharing, whiteboard, and file sharing capabilities.

Participants can return to the main meeting at any time by clicking Return to main meeting in the toolbar.

If a participant loses connection and rejoins the meeting, Teams will ask if they want to return to their breakout room.

Tips for Running Effective Breakout Sessions

Assign a facilitator to each room: Before opening rooms, announce who will lead each group.

Give clear instructions before opening rooms: Use the Announcement feature to share the task, time limit, and expected output.

Keep groups small: Three to six participants per room maximizes engagement.

Use a shared document: Drop a link in the breakout room chat so all groups contribute to the same collaborative document or whiteboard.

Set a timer: Use the automatic timer feature so participants know exactly when they will return to the main meeting.

Debrief immediately: When rooms close, ask each group for a 60-second summary before moving on.

Conclusion

Breakout Rooms are one of the most powerful tools for making large virtual meetings actually productive. Instead of passive attendance, participants are active collaborators. Instead of one voice dominating, everyone contributes.

In 2026, with Copilot automatically summarizing each room and compiling insights across groups, the administrative burden of running breakout sessions has nearly disappeared. Set up your next training, workshop, or all-hands with Breakout Rooms and experience the difference that structured small-group work makes to participant engagement and meeting outcomes.
