Exchange server keeps sending email every hour to external recipient RRS feed

  • Question

  • Hello everyone

    I had a user send an email to about 40-50 people in the BCC field. She used her address in the To field. Now someone she sent it to is complaining they are getting the message every hour.

    I figured it was because one of the recipients failed and while it tried to redeliver, it got delivered to the others again. So, I check the queues and sure enough there are quite a few on Retry mode. I clear those, have them send an NDR to my user and think everything is good.

    A day goes by and the same external recipient writes in that they are still getting the email. So what to do?

    I've checked the queues.There are no queues being displayed except the Submission queue which is empty.

    Any ideas? This is Exchange 2010. The message was sent with Outlook 2007.

    Thanks for any help!

    Check your SMTP protocol log and see if there's a message that's being
    sent to that person at that time. Verify that the end of the message
    receives a 2XX status code from the receiving server.

  • Thanks as always Rich. Stupid me forgot all about that. I checked message tracking logs and only came up with the one message sent to him originally as a member of the BCC field.

    I have enabled SMTP logging on my Send Connector and will check if there is an outgoing connection on the hour to his mail server. If I don't find this happening, is it safe to tell this organization the problem is on their end? Any idea what would cause that?

    Thanks again!

    If you don't see the message leaving your server then, yeah, I'd say
    the problem is at their side. :-)

  • Hey Rich, I checked the logs in the morning and did not see a single message sent to the address the person is claiming to get the emails to nor a single email sent by the original sender so I instructed the user to contact their local IT staff. Thanks again!
