XADM: Exchange Server 5.5 Users Cannot Log On to Their Mailboxes After Active Directory Connector Replication

After an Active Directory Connector (ADC) replication, users cannot log on to their Exchange Server 5.5 mailboxes. They receive an access denied error message. If you look at the permissions on the mailbox in the Exchange Server 5.5 Administrator program, you see that the mailbox owner right has been removed from the permissions for that account and that the user's role has been changed to Custom.

The recipient connection agreement has been changed from a one-way agreement to a two-way agreement.
