I found the answer myself, you need to add an ?action=delete argument to actually delete the user. Otherwise, the account is “disassociated” with the current license and becomes an “free account” for the user. Follow-up question. I tried taking a disassociated account and changing the email id, but it appears that the account still exists under the old email address? Once an account is disassociated, is there any way to delete it? Even using the Zoom client and either the old or the new email?
