  • Exchange 2003 email randomly not delivered via routing group connector

    We have a multi site environment under one Exchange organisation. Each site has their own exchange server running Exchange 2003. Each site has a routing group connector to the other site set up.
    On one site (Site B), sporadically, email from another site (Site A) is not delivered. On Tracking Centre I can see the email leaving Site A but on Site B its says delivered but recipients do not receive it. (The attached screenshot shows Tracking on one email that was sent to a distribution list of 30 people but only delivered to 2!)
    I do not see them sitting in any queue on either server. If I then restart the System Attendant and Information Store on the Exchange server on Site B then these messages will be delivered.

    Any ideas?

    Usually the first port of call for emails going missing is the AV/AS software. Do you have anything in that dept?

      We use McAfee and I have checked the anti-virus software and there is nothing held here. It seems to be held in Exchange in a queue that I cannot see as when I restart Exchange services the mails will then be delivered

      Thanks

        Exchange passes the email via SMTP. Therefore if you restart the SMTP Server Service does that release the messages?
        Exchange does have a hidden queue that you cannot see, it wouldn't be seen in the queues. Furthermore if it was being blocked by AV/AS then that is usually seen in Message Tracking as the message stopping at the categoriser. Although it can also be caused by file level AV software scanning something it shouldn't do.

        When you restart the services, which end of the routing group connector are you restarting? Does it matter?

          I restarted the SMTP service but this did not release the mails.
          It is on Site B that I restart the services, the server that mail is being delivered to. The issue seems only to be on this end and I am not aware of there being an issue with mails from Site B to A.
