  • The Host must create the breakout rooms with correct emails addresses. You can get correct email address for students in a course from SOLAR.

During the meeting

  • If host/participant are on updated versions of the Zoom app and a pre-assigned participant joins after the breakout rooms are opened, they will now be automatically prompted to join the breakout room/sent to the breakout room
  • If a participant joins after you (the host), they will not be automatically assigned to the breakout room you specified when scheduling the meeting.

Missing Students

If you see that your assignments are missing students in the Breakout rooms and "Open All Room" is not clickable:

This will re-assign students according to your breakout room setup.

Unassigned Students

Students must be signed into the Zoom Client and on a supported device for them to be pre-assigned. 

If there are unassigned students, Zoom will alert you:

This can happen if a student was omitted during the pre-assignment breakout room setup or if a student leaves (i.e. internet down) and then comes back into the meeting.

To assign the student, click More > Breakout Room

Click Join next to the Breakout room and enter the unassigned student's name. Do this until there are no unassigned students.
