From Exchange 2007 EMC, I granted a user (and my profile, as well as administrator) full access to an old employee's mailbox. But when trying to set up the account in Outlook 2007, a prompt pops up asking for credentials. If I use my credential or administrator credentials, it still won't give us access.
I've set up other mailboxes in the same fashion and didn't have any problems. Is there another place I need to go to? This user's profile is not disabled.
