As a meeting host, you can split your meeting participants into breakout rooms when scheduling the meeting. This can be useful if you already know how you want to split up your participants.


  • Only 200 participants can be pre-assigned in Zoom meetings.
  • If you start the meeting from the Linux client or Zoom Mobile App, you will not be able to see your breakout rooms with pre-assigned participants.
  • In order for pre-assigned breakout rooms to work, attendees will need to sign in to their Zoom account associated with the email placed in the CSV upload.
  • If you have registration enabled and external participants register for the meeting, you need to assign them to breakout rooms during the meeting.

Pre-assigned breakout rooms only work if the users sign in to their Zoom account associated with the email provided on the pre-assignment. One way to make sure that users sign in is to require authentication for your meeting. This makes is so that anyone that is not signed in to their Zoom account when clicking the join link will be prompted to sign in in order to gain access to the meeting.

Students must sign in using SSO (Single Sign On = BlazerID/Password). Here is a guide on how to sign-in to Zoom on phone or computer when joining a meeting.

  1. When scheduling your meeting, check the box for Only authenticated users can join (A) in the meeting options and choose which authentication you want to accept (anyone with Zoom account or just UAB Zoom accounts).
  2. Check the box for Breakout Rooms Pre-Assign (B) and choose which method you would like to use to pre-assign breakout rooms.
    • Create Rooms (C) allows you to use the Zoom interface to create rooms and assign people by typing in their @uab email address. This option will only allow you to type in email addresses of users that have created a Zoom account with UAB.
    • Import from CSV (D) allows you to create an worksheet with the desired group names and emails and upload it for pre-assigning. This option allows you to assign users internal and external to UAB.

You can create breakout rooms, name the rooms, and assign users through the Zoom Web portal. Note: When pre-assigning participants using the web portal, you can only pre-assign internal Zoom users that are in the same account ( email addresses).

  1. Click + Create Rooms shown in the previous step to open up the Pre-assign web portal.
  2. Click the + (A) button beside Rooms to add breakout rooms [limit is 50].
  3. Hover over the room and click the trash (B) icon to delete a room.
  4. Hover over a room title and click the pencil (C) icon to change the name of the room.
  5. Add Users (D) to a room by typing their name then clicking the full name that appears in the list.
    Note: If a user does not appear here, they do not currently have a Zoom account with UAB. You can direct the user to create their account or you can use the Import from CSV option.

  6. Hover over an assigned participant to see the option to Move or Delete assignment (E).


  • Use @uab emails for users internal to UAB
  • Emails should be all lowercase
  • Some users have alias’s instead of This email address is being protected from spambots. You need JavaScript enabled to view it.. Check the UAB Directory to know what a user’s email is.

  2. Download the template CSV (A) worksheet to see the example.
