pre-assigning people to break outs

[wmertz]

I'm trying to pre-assign people to their breakouts with their emails before my meeting starts but when I test launch the zoom meeting, no one is assigned to their groups, the rooms are empty. Do people need to be zoom users? or have registered for the meeting? How do i pre-assign people and make them stick? Thanks! (I will have a mix of external zoom users and non-zoom users when i actually go live with the meeting)
