As a host or cohost, you can remove a participant from a breakout session before the sessions start.
If you need to remove a participant from a breakout session after the sessions have started, you must remove the participant from the meeting.
Breakout sessions are available on WBS40.9 and later sites. To find out which version of Webex Meetings that you're using, see Find Your Cisco Webex Meetings Version Number.
If the Breakout session assignment dialog box isn't already open, click Breakout sessions to open it.
In the list of breakout sessions, locate and hover over the participant that you want to remove, and then click Remove.
