I have a bit of a problem with one of my users. His voicemail was working until recently when his mail account was moved on to another server. Since then I have been unable to change the exchange server that his account is pointing to in Unity and unfortunately I can?t delete him to then clear the system and re-create him. For some reason on this user the delete option is greyed out.
Do you have any ideas as to how I can get this account functioning again?
