We recently migrated over from our GSUITE instance to another. We had blabla.com as our domain. We wanted to move that domain over so as a placeholder for the accounts, we put in a post.blabla.com in our GSUITE. Within our Jira cloud instance most account emails accounts stayed blabla.com, while just a small handful changed to post.blabla.com. We have tried to changed the emails back but it is saying that the email addressed is associated with another account. Any help or idea?
