Here is the deal. We recently migrated Exchange 5.5 to Exchange 2000. All seemed well, until I tried to access other people's mailboxes. The users themself can retrieve their mail. I am in the Domain Admin Group. I used to be able to see everyone's mail . So I went into the mailbox rights and sure enough it says that Domain Admin can do anything he want's but the boxes have grey check marks. I tried to re-add the Domain Admins but it says I can't because it propogates from the parent object. I've been trying to find the parent object or a way to fix this, because sometimes I need to go into people's mailboxes to assign Delegates.

Anyone with a suggestion, I would appreciate your ideas.
