Hi, we recently lost an Exchange server which had its own mailboxes on it and was part of our Windows Exchange Server 2003 organization. We migrated the AD accounts to our parent domain and retired the DC using dcpromo /forceremoval. However, when we try and Create Exchange mailboxes for the new AD accounts, the SMTP is set to firstname.lastname@example.org. Editing this does not work and we get the error message:
This email address
We have a recipient policy on our Exchange server.
We have manually removed the dead Exchange server from the organization using ADSIedit successfully but it seems that there are still replication references to the objects.
