Exchange Routing Issue?

By simon.pendlebury@ticketli ·
I am having an absolute nightmare with my Exchange 2003 server.

We purchased a new server and I followed the instructions on Technet to the letter to migrate Exchange onto this. The two servers have been running together for the last few weeks and everything seemed to have replicated onto the new server.

Yesterday, one of the drives in the old server started to fail, so I had to remove the old server sooner than I had hoped and worked late. Before I uninstalled Exchange on the old server, I dropped all the Exchange services and made sure everything worked. It all seemed fine.

Today however, we have had a problem where when a user tries to send an internal email to any of a number of accounts, Exchange tries to route the message externally. These messages remain the queue for a time and then an NDR is returned saying that the email doesn't exist in the organisation.

I really don't know what the issue could be here - I have checked everything I can think of.

I don't know if the issue is related to the fact that we have two internal email domains in use - one is used for external main and the other is the AD organisation. All users have an address in each of these domains.

I'm not even sure if I missed a setting from the old server, or if this is even an AD problem (as the old server was a DC as well - though it was demoted cleanly).

Any help would be very much appreciated.

In ESM, Repoint the RUS to a working DC and rebuild RUS.

Worked around it....

Thanks for the reply.

I ahev managed to get around the problem by creating a few alternative groups and moving email addresses around. Not ideal, but it has worked in the short term.

I did try updating the RUS, but that doesn't seem to have made much difference.

Any other ideas?
