Exchange 2010

ok, we had a problem with mcaffee stopping emails on the server, but may not be that. i'd take a look at the receive connector on the exchange 2010 server under server config/ hub transport. i'd also take a look at the relay settings on exchange 2003.

I think the problem is with the routing group connector between the two exchange servers as if I have a look at the connector in ESM in 2003 I can see all the messages that have failed to reach me and they sit there saying pending and retrying.

thats is exactly the same problem we had. try disabling the antivirus and see if they then send.

No joy with this I'm afraid. I even tried disabling the Windows Firewall but still doesn't work. Just refusing to pass the email on from our 2003 box to 2010.

have you checked the permission groups on the exchange 2010 recieve connector? i'm assuming there are no event logs showing a problem?

theres some helpfull info here too http://social.technet.microsoft.com/...1-35350dd01e23

You are an absolute legend mate. That post led me to some information about the SMTP smart host information and yes indeed we had a smart host configured on our E2K3 server and an internet mail connector. I removed the smart host info from the SMTP virtual server and bingo emails came flooding through.

Cheers!

glad you got it working

And I'm back again lol. Sending and receiving emails between Exchange 2003 and Exchange 2010 mailboxes now no problem since removing that smart host entry on the SMTP virtual server. Unfortuantely now I cannot send emails to anyone outside of the organisation. We have an internet mail connector on the exchange 2003 box and I can see Exchange 2003 pass it the emails through the queues but after trying and trying it drops into the messages queued for deferred delivery box.

[glen_j]

did you add the smart host to the smtp connector after removing it from the virtual server?

Nope working again now! I'll leave you all in peace now with this one but a MASSIVE thank you to everyone who helped.

Many thanks
Adam.
