This is a disabled user who used to be a system admin. We're managed with AD at this point but looking at his user account it's "Confluence Internal Directory" which is I guess a fallback for if AD broke, he could still get in.
His email address is the same as the administrator email and cloud migration doesn't like that.
So, I need to change his email address. Can't do it from the user directory. "You cannot edit the Full Name or Email fields as you are not using Confluence to manage users" but this is not listed as an AD account.
So, is it sounding like this should somehow be actually an AD thing, despite the system indicating otherwise?
