We have a Client wth the following conditions:
Three (3) Servers, all Wndows Server 2003 Enterprise.
Server A: PDC and GC
Server B: BDC, GC and Exchange 2003 Ent.
Server B: ERP and SQL
Recently, a consultant performed the following, in this exact order:
Installed Exchange 2003 Ent on Server A in preparation of decommissioning Server B entirely.
Demoted Server B, leaving Exchange intact.
Replicated "some" objects, but others apparently displayed as "local modified" on for Server A.
Moved all the mailboxes and Public folders (only had two), then closed down Server B. They did a few internal testing, and were satisfied. They then uninstalled Exchange 2003 from Server B and pulled the plug.
At one point in time, Server B hosted mail for two Domains: Domain A and Domain B. Domain B was purchased by an outside Company, and references on Server B were removed. They did have problems sending to recipients at Domain B for some time, but apparently got that corrected. Now, with only Server A running Exchange, they are again having problems sending to Users at Domain B. The error is as follows:
real.user@DomainB.com on 10/24/2011 1:23 PM
The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
As you can see, Server A is trying to locate the recipient that "use" to reside in this organization, but fails. The Recipient list looks ok, and the Domain only hosts mail for Domain A. Domain B is no longer there. However, we do "see" references in various public folder locations for Domain B. How do we remove those, get mail working again through to Domain B and clean up this mess in Exchange?
