Exchange 2010

Background:
I finished an upgrade/migration from Exchange 2003 to Exchange 2010 (over a year ago).
The old Exchange server was also 1 of 3 Domain controllers in the forest.
Old Exchange was removed and the server was demoted to a member server.
I followed this excellent walk thru from Demazter

demazter walk through

I still have some errors that reference the oldEXserver, i ran ExBPA and it thinks that oldEXserver is still there.

MSExchangeTransport Event ID 5006

Cannot find route to Mailbox Server CN=oldEXserver,CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ourcompany,DC=local for store CN=Mailbox Store (oldEXserver),CN=First Storage Group,CN=InformationStore,CN=oldEXserver,CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ourcompany,DC=local in routing tables with timestamp 2/13/2013 4:06:25 PM. Recipients will not be routed to this store.

MSExchangeTransport Event ID 5020

The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003 oldEXserver.ourcompany.local in Routing Group CN=First Routing Group,CN=Routing Groups,CN=First Administrative Group,CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ourcompany,DC=local in routing tables with the timestamp 2/13/2013 4:06:25 PM.

I am preparing to totally remove the oldEXserver from the domain, and would like to remove this error prior to that, if only to satisfy my curiosity as to how this happened.

Thanks in advance for any help...

Sounds like there are artifacts in AD.  Probably just use ADSIedit to clean up.

Run ADSI Edit, connect to a DC and using the Naming Context “Configuration” & expand following items:
Configuration Container -> CN=Services -> CN=Microsoft Exchange -> CN="Your_Organization_Name” -> CN=Administrative Groups -> CN="Your_Administrative_Group_Name” (Probably - CN=Exchange Administrative Group (FYDIBOHF23SPDLT)) -> CN=Servers

Right-click the Exchange 2003 server object which you want to delete, and then click Delete & click Yes in every adsiedit dialog box that prompts you to confirm the deletion.

!!!WARNING only delete the 2003 server object in the CN=Servers group not the whole tree - doing so will unleash a world of hurt.

Seems there is a RGC still not removed

Get-RoutingGroupConnector
If you see any RGC listed

Get-RoutingGroupConnector | Remove-RoutingGroupConnector

Also ensure that no Send connector has Exchange 2003 in SourceServer Tab in EMC

@jpower5000

CN=Configuration,DC=ourdomain,DC=local
CN=Services
CN=Microsoft Exchange
CN=First Organization
CN=Administrative Groups
CN=First Administrative Group
CN=Servers
CN=TheOldExchangeServer

So i can delete CN=TheOldExchangeServer
@rancy

The RGC's were removed long ago, and the send connectors do not reference the old Exchange
server.

Can i also delete:

CN=First Administrative Group

and everything below that, every folder in the structure is empty.

Pro & Cons?

No its recommended to keep as if once deleted you cant ever bring back Exchange 2003 or so .... i too would say as it hasnt affected anyone till date
