If you’re not staying on top of your Exchange
5.5 organization’s directory replication, you can end up with
orphaned objects. Orphaned objects remain in a remote site even
after you’ve deleted the object from the original site.

Orphaned objects typically occur when directory
replication breaks down, someone deletes objects from a site, and
the deleted objects don’t get the chance to replicate. Once the
tombstone period expires on the deleted objects, replication no
longer occurs even after directory replication starts working

The best way to prevent this problem is to
check for proper directory replication on a regular basis. But if
you do encounter an orphaned object, it’s possible to remove it
from the directory. Follow these steps:

  1. Open the Exchange 5.5 Administrator program
    in Raw mode (Admin.exe /r).
  2. Select the orphaned object, open its raw
    properties, and make note of the Obj-Dist-Name and Object Version
  3. Using the Obj-Dist-Name attribute from the
    orphaned object, re-create the object in the original site.
  4. Make changes to the object, and apply the
    changes until the Object Version value of the re-created object
    exceeds that of the object in the remote site.
  5. Either wait for the newly re-created object
    to replicate throughout the organization, or force replication. To
    make sure replication has occurred to the remote site, check the
    Object Version value.
  6. Delete the object from the original site, and
    replicate the change.

The deletion will now replicate to the remote
site and remove the formerly orphaned object.
