Zoom breakout rooms are powerful tools for facilitating small group discussions, collaborative work sessions, and team activities during virtual meetings. Pre-assigning participants to breakout rooms before your meeting starts can save valuable time and ensure smooth transitions. This comprehensive guide will show you how to create and manage breakout rooms in Zoom before your meeting begins.

What Are Zoom Breakout Rooms?

Zoom breakout rooms allow meeting hosts to split their Zoom meeting into up to 50 separate sessions. These smaller meeting spaces enable participants to collaborate in groups, conduct workshops, facilitate classroom discussions, or organize departmental meetings during larger company-wide events.
