Hello @StateWideMLS ,
The issue is that the email addresses are going to be used as the initial usernames for their account logins. Each account's login will need to be setup individually, then the users will need to finalize their login (including adding MFA preference), then they'll need to update their username to something unique other than that email. Then repeat this process for the remaining accounts.
