How can I remove the Administrator Mailbox from Exchange 2010? I don't want to delete the whole user account because I need Administrator to access the Server, but Administrator shouldn't have any mail addresses assigned.
Background: We use Eset Mail Security which is getting licenced per mailbox count. There is also a tool from ESET to check current mailbox count: http://kb.eset.com/esetkb/index?page=content&id=SOLN2425 To avoid paying for unused mailboxes, I want to disable Administrator's (and also other unused) mail boxes.
Thanks!
