Exchange 2013 transport rule issue

    Question

  • Dear Support,

    I have created the transport rule in exchange 2013 i.e. when one external user (abc@gmail.com) send email to one internal user i.e. (Support@contoso.com) then that email get blocked with explaination but issue is external user not able to receive any notification email regarding blocked email.

    If I created the same rule with internal user then they are getting the notification, please let me know what could be the issue why external user failed to trigger the notification.

    Exchannge Version: Exchange 2013 15.0.847.32

    Appreciate your quick response regarding the same.

    Regards,

  • Hi,

    Please post the detailed transport rule for troubleshooting. Screen shoot is better.

    In the transport rule, how do you identify that external user?

    Besides the transport rule, will external sender receive NDR messages normally?

    Best Regards.

  • Hi Lynn,

    Yes user received the NDR message normally.

    I have added the external user as mail contact and added as sender.

    Bad idea. Just enter the senders SMTP address in the transport rule , don't use a mail-enabled contact. Instead of "The Sender Address is..." use the predicate "The sender address includes" and enter the SMTP address. Delete the mail-enabled contact.

  • Hi Lynn,

    I already tried this but it was not working so I created mail enabled contact.

    And what does message tracking show?

    You need to post the exact rule syntax so we can look at it.
