    I am trying to send mail from E2k7 to My E2k3 Server.

     

    Under the Queue Viewer I get the above error. Mail from the 2k3 Exchange flows to the Exchange 2k7.

     

    I have tryied changing the Microsoft Transport Service Logon to Domain Administrator but no joy.

     

    Have made sure the Exchange 2k3 Server Uses Windows Auth - No joy

     

    I had to manually create the  initial route connector as it didn't do it automatically

     

    The proplem I have encountered is very similar to previous posting

     

    451 5.7.3 Cannot achieve Exchange Server authentication

     

    Thanks in Advance                 - very stumped!

    Enable Windows Integrated Authentication Mode in Exchange 2003 Default Virtual Server.

    In my case changing the FQDN

     for the SMTP Virtual server on the 2003 box so that it was the FQDN of the 2007 Server fixed the problem.

    Hello All,

    I'm getting the same error. I just finished moving all my mailboxes from Exch2k3 to Exch2k7. There was a RGC that existed between my Exch2k3 Admin group and Exch2k7 admin group. I deleted the RGC on Exch2k3 and recreated it on Exch2k7 using this powershell cmdlet:

    New-RoutingGroupConnector -Name "Exch2k7-To-Exch2k3" -SourceTransportServers Exch2k7HT01,Exch2k7HT02,Exch2k7HT03 -TargetTransportServers EXCHBH1,EXCHBH2 -Cost 1 -Confirm $false

    Now mail destined for users in the Exch2k3 Administrative Group are sitting in the queue with Delivery Type 'SmtpRelayToTiRg' and Last Error of '451. 4.4.0 Primary target IP address responded with: "501 5.5.4 Auth command cancelled.." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts.

    I get this events in the application log

    Source: MSExchangeTransport
    Category: SmtpSend
    Event ID: 2017
    Type: Error
    Description: Outbound authentication failed with error -2146892976 for Send connector Intra-Organization SMTP Send Connector. The authentication mechanism is Gssapi. The target is SMTPSVC/EXCHBH1.MYDOMAIN.COM.

    I've been working with Microsoft Premier Support for 2 days trying to resolve this issue but still no solution yet.

    Any help will be very much appreciated.

    Hello All,

    I have modified the FQDN of the default smtp virtual server properly on E2k3.

    Then restarted the SMTP service on E2K3.

    Started working.
