During replication, the Active Directory Connector (ADC) may not match or merge a Microsoft Exchange Server 5.5 mailbox to its corresponding Active Directory object.

This behavior may be caused by problems in creating objects in a remote domain. For example, suppose two domains exist, Dom1 and Dom2. There is a Connection Agreement between Exchange Server and Dom1. The Exchange Server 5.5 mailbox may have an Active Directory object associated with it that is in Dom2. If the ADC does not have rights to create objects in Dom2, then it cannot effectively match or merge these two objects.


To identify this situation:

  1. Set Diagnostic Logging for Replication to "Minimum:"
    1. In the Active Directory Connector Management Microsoft Management Console (MMC) snap-in, open the properties of the ADC that owns the Connection Agreement.
    2. Click the Diagnostic Logging tab.
    3. Click Replication, and then click Minimum.
  2. On the Connection Agreement Schedule tab, click to select the Replicate the entire directory the next time the agreement is run check box.

    NOTE: When you set this option, everything between the target and source containers replicates, setting the known USN to 0. This logs events that detail that the ADC does not have write permissions to the target domain.

To address this problem, you must set permissions on the target domain to allow the ADC to write to it, or you must configure another Connection Agreement to the target domain with appropriate permissions.
