We are in the final stages of rolling out a new Exchange environment built on a resource forest. As far as account delegation goes I am interested about how permissions are assgined. Since all mailboxes have disabled users created in the resource forest and are linked to master accounts in the login domain how do you add full access permission to a mailbox in the resource forest to an account in the login domain? Do you grant the access to the disabled users with the linked account or do you need to point the permissions back to the user account in the login domain? Thanks for any help.
