Exchange 2003 - to 2010 migrate testing, unable to send internally.
Now before you ask, yes I have browsed the already posted questions and solutions about this topic, but none seem to fit my situation exactly.
We have a Win/Exch 2003 server running which holds most of our mailboxes. Everything works fine.
We have deployed a Win 2008 R2/Exchange 2010 box to use for testing before we migrate the rest of the mailboxes to it.
The move of the test mailbox went fine.
From this mail box, we can send and receive externally, but we can't send internally. Only receive.
We have a send connector configured, and we have removed the original RGC, and recreated it. But still no luck.
You advice appreciated.

Are you getting an error when trying to send? When you track the message, what do you get in the logs?

It just stays in the Exchange 2010 queue. I have attached a screen shot of the errors.

it looks like there are DNS issues that are affecting mail routing from the 2010 server to the internal domain. Check to ensure both servers have MX records properly configured. Check the send connector configuration for the internal domain (you should have 2 connectors, one for each domain). Check the Edge Transport config, and make sure it is configured to use the correct DNS server. run nslookup and make sure you can resolve the local domain. you can also look at http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/f90ddbd9-3ed6-4559-9ad9-cc6806fdb4e8/

OK Im a bit stupid, so bear with me..
1. I don't know much about internal MX records. Under the Send connector it is ticked to " Used the DNS "MX" records to route mail automatically, Enable Domain Security is not ticked. That's aboput as much as I can tell you about internal MX records.
2. There is only 1 send connector, I think it was configured as a custom connector, using an address space of *, the rest were just the default I think...
3. There is only 1 domain, 2 Exchange servers, but 1 domain.
4. Were not using Edge transport.
5. NSlookup does resolve the other mail server properly.

let try this:
1. Send internal email between user on local Exchange 2003 database. Able to recieve or not?
2. Send internal email between user on local Exchange 2010 database. Able to recieve or not?
3. Send internal email between user on Exchange 2003 database to Exchange 2010 database. Able to recieve or not?
4. Send internal email between user on Exchange 2010 database to Exchange 2003 database. Able to recieve or not?

The only one that doesn't work is number 4.
I can't send from the 2010 database to the 2003 database.

Have you tried by re-creating RGC between 2010 and 2003 ?, You should have a two-way Routing Group Connector (RGC) when you introduced 2010 into your 2003
Create Additional Routing Group Connectors from Exchange 2010 to Exchange 2003:

Yes we have recreated it. There is a client and a default one from memory, I don't have it in front of me ATM.

Looks like that was it. Have added the FQDN of the 2003 box, to the host file of the 2010 box, and it seems to have solved the problem.
More great work from everyone, much appreciated!
