we have one user whose email was linked to AD and was say email@example.com
He also has access to another email say firstname.lastname@example.org - within same exchange server. I created a new user with his name and then gave full permissions to user123 so he can access 2 accounts.
But now he wants user123@xyz as his main email. Whats best way to change his main email address ?
hope above makes sense lol
As at present if he creates a new email its always abc.com and not xyz.
