If you can't add someone with an @stonybrook.edu email address as an alternative host in Zoom (especially around the start of the semester), ask that person to sign out and back into Zoom to reclaim his/her Zoom license and then try adding them again (see below). 

Note: You can only add other licensed @stonybrook.edu users' email addresses as alternative hosts, so if the person you're trying to add signs out and back into Zoom and you still can't add them as an alternative host, that person might have a Basic instead of Licensed Zoom Account (Affiliates, for example, have Basic Zoom Accounts).

• Sign out and back into Zoom app (have the person you're trying to add as an alternative host follow these instructions)
