User A has full access right to User B's contacts. In Outlook User A's contacts, all of User B's contacts are listed. However when hitting the "to" button the various lists of contacts are not present. What we've tried:
-giving ownership to each address book in User B's contacts
-adding User B's mailbox to User A's control panel mail properties
-giving User A full access rights to User B's mailbox in Exchange 2007.
Any Ideas? Thanks.
