    We have an Exchange 2010 SP2 environment. I have been setting up various scenarios for testing forwarding email to remote domains, and attempting to understand the effects of certain settings. That being said, somewhere along the way a bunch of messages got deferred after expansion and now I don't know how the heck to access those messages to try and get them processed. Basically, here's what I'm looking at in the tracking log viewer:

    Can someone explain to me what the heck I am looking at here? It looks like they were deferred before they even got to transport. So great, if they're not in any queue, how in the world can I get at these messages? Is there a way to force them to retry or do I have to wait some indefinite period of time for them to retry automatically? Is there anywhere I can view status or logging information?

    A "defer" DSN was sent. The messages should still be visible in the
    queue viewer.

    The "agent" is a transport agent, so they got that far.

    Is it possible they were swallowed by anti-virus or anti-spam
    software? When things go missing it's usually in the categorizer and
    that's where some of those agents work.
     
    Have you checked the agent log to see if there's information there?

    I never received a DSN and none of the messages were available in the queue viewer. Here's the scenario:

    I had temporarily disabled the AutoForwardingEnabled option on the default remote domain. I also set up a test mailbox and configured the ForwardingSmtpAddress setting to a personal account on GMail. I then used my (Exchange) mailbox to send an email to the test account. As presumed, it didn't get forwarded, but I also did not receive an NDR. I would think the NDR should have been sent to my own mailbox since I was the original sender and the forwarding scheme is essentially a redirect. Is it possible that the NDR went to the test mailbox rather than my own? That doesn't seem logical to me, but I could see if that were the case, then the DSN likely got stuck in a loop as it was returning to a forwarded mailbox.

    Also, we are not using the anti-spam agents on hub transport. Some are enabled on our edge servers, but the tracking log doesn't show that they were handed off, so I don't think that's the case either.

    Finally, this morning I ran a delivery report on those emails and they still list as "pending":

      Message delivery is taking longer than expected. There may be system delays. For more information, contact your helpdesk.

    Then the messages are discarded if that autoforward property is
    present in the message.

    No, you won't get one, either. The message is discarded. No
    notification is sent.

    No DSN was sent. The message was sent to the write-only memory cache
    (A.K.A. the "bit bucket"). ;-)

    What's your expiry time? Has it elapsed?

    Thanks Rich. I think I just assumed that if the message were not getting forwarded, nor a copy left at least in the destination Exchange mailbox, that I would receive an NDR alerting me that, hey, the recipient didn't get that very important test email!

    But alas, it could be the way I had the recipients set up, who knows. Either way, thanks for clarifying my questions.
