Exchange attributes are improperly matched to Active Directory objects.

For various reasons, Exchange attributes may be mismatched with Active Directory objects. This usually occurs if multiple mailboxes in Exchange 5.5 have the same primary Windows NT account, but those mailboxes were not marked to identify which mailbox should be matched to the user account in Active Directory.

To resolve this issue, use Exchange Task Wizard to remove the Exchange attributes and then properly prepare the Exchange 5.5 directory by marking resource mailboxes. Finally, you need to run your properly configured ADC Connection Agreements.

Warning   Do not attempt to remove Exchange attributes until you have discussed the need to perform this procedure with Microsoft Product Support. For the most up-to-date information about how to remove Exchange attributes, see the Microsoft Knowledge Base .

To properly match Exchange attributes with Active Directory objects:

  1. Stop the Active Directory Connector service.
  2. Use Exchange Task Wizard to remove Exchange attributes from the Active Directory objects you want to reconnect.
  3. Ensure that your connection agreements are properly set up.
  4. Remove the ADC-Global-Names attribute from the mismatched mailboxes in the Exchange 5.5 directory.
  5. Use the NTDSAtrb utility to identify and mark resource mailboxes
  6. Run your properly configured ADC Connection Agreements.
