Exchange 2010 Routing Issue

I am currently migrating 4 servers (4 administration groups) from exchange 2003 to 2010.

I have successfully migrated the first 2003 server (ukmail) to 2010 (ukex). I am now migrating the second 2003 server (nymail) to 2010 (nyex) and have mail flow issues.

Whenever I send an email from nymail (2003) to nyex (2010), it goes via ukex (2010) server. I have configured a legacy routing group direct from nymail to nyex.

Does anyone have an idea why this could be happening?

Thanks in advance
Rob

Remove the connectors completely and recreate them.
While you do that email will queue, but it will force the routing tables to update.

Smart host on SMTP virtual server would be my first guess.
Are the routing group connectors you configured bi-directional?
Are the Exchange 2003 servers in seperate routing groups? If not then Exchange will treat them all as one.

Just checked, no smart hosts setup on 2003 server.
Yes the routing groups are bi-directional.
Yes the 2003 servers are in separate routing groups.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Have you restarted any services on the Exchange 2003 server since creating the connectors? It could be that the connector didn't create properly - that happens all the time.

The old turn it off and on again :)
Just tried that, with no success.

Any more ideas?
