    I am unable to send email externally from exchange 2010 mailbox. Internal mail works fine and I'm able to receive external mail to the Exchange 2010 mailbox.

    Error: A matching connector cannot be found to route the external recipient

    RGCs were created using the following commands:

    New-RoutingGroupConnector -Name "2010-2003" -SourceTransportServers "2010hub.example.com" -TargetTransportServers "2003server.example.com" -Cost 1 -Bidirectional $false -PublicFolderReferralsEnabled $true

    New-RoutingGroupConnector -Name "2010-2003" -SourceTransportServers "2003server.example.com" -TargetTransportServers "2010hub.example.com" -Cost 1 -Bidirectional $false -PublicFolderReferralsEnabled $true

    However I've also tried with the -Bidirectional $true.

    Integrated windows auth is set on the 2003 virtual smtp and secure channel is disabled and no smart host is in use.

    I've been scratching my head with this for a while, can microsoft gurus help?? From what I've read, mail flow from 2010 to the outside world should happen automatically and without having to create a 'send connector'.

    Thanks

    Matt,

    You have to have a send connector that either routes to a smart host or sends to *, you can do this through the EMC or the shell. Here is an article that can assist you:

    It was my understanding and that of other Microsoft techs that a send connector is not required. As long as the RGCs are in place the external mail will go out through the 2003 box via the RGCs....

    Is this now not the case? :s

    By creating a send connector on the 2010 box, the queue will be moved from the 2003 box to the 2010 box and all mail will go via Exchange 2010. I want to avoid this until we are ready to switchover.

    Thanks

    Hi

    Create the send connector from 2003, System manager instead.

    Then you will be fine

    Thankyou Jonas, I can't believe it was as simple as that and that nobody mentioned it until now!

    Nice one!
