  • Did you try after restarting the both the servers? If not please try that as well
    Can you please post the result of command

    Get-RoutingGroupConnector

    Can you see the emails stuck in the queue in Exchange 2003?
    If not can you enable logs on default receive connector and check logs in exchnage2010?

  • Can you send a test email from Exchange2003 to Exchange2010 and post the error?

    I suggest you please restart the exchange server and try again if you created the bidirectional RG-Connector.

  • Can you please post the result of command?

    Get-RoutingGroupConnector

    Restart Exchange2010.

    If the problem persists after restart please remove the Routing groups connectors and create a new bidirectional Routing Group connector and check. Or delete your old Routing group connector would be enough and restart exchange transport service

  • Did you try what I mentioned in my previous posts?. If not please delete both and create a new bidirectional RGconnetor.

    http://technet.microsoft.com/en-us/library/aa997292(v=exchg.141).aspx

    New-RoutingGroupConnector -Name "NameOfRG" -SourceTransportServers "Ex2010.contoso.com" -TargetTransportServers "Ex2003.contoso.com" -Cost 10 -Bidirectional $true -PublicFolderReferralsEnabled $true
    FYI you are maintaining a product that has left extended support.

  • Dear MAS,

    Issue resolved after doing one strange change.

    on my 2003 smtp default virtual server ,their was smart host which i removed.

    then i configured a seperate connector for internet then everything is okay.

    The issue is if 2003 default smtp server have smart host configured it will break communication between 2003 to 2010.

    But your resolution was also commendable.So i will mark as answer ed
