Incoming messages are queued forever RRS feed

  • Question

  • We run one Exchange 2016 server on Windows 2012 R2. In Mid May we found one user mailbox "user1" was corrupted. So we backed up all his emails, deleted the mailbox, and recreated a new one. The user also had one alias called "alias1", and it has been added to the account as well. 

    Then after about a month, I found all internal emails are working fine, but incoming emails are working only with user1@mydomain.com, only 1 or 2 of every 10 incoming emails to alias1@mydomain.com are received, all the other emails received by Exchange are just queued somewhere unknown. For example I queried two emails from the same sender to alias1@mydomain.com below.

    The one still queued somewhere after nearly a month:

    6/18/2019 9:30 AM exchange.mydomain.local
    Message was received by exchange.mydomain.local from myincominggateway.com.

    7/11/2019 9:59 AM exchange.mydomain.local
    Message delivery is taking longer than expected. There may be system delays. For more information, contact your email admin.

    The one received 3 hours later on the same day was however delivered immediately:

    6/18/2019 12:05 PM exchange.mydomain.local
    Message was received by exchange.mydomain.local from myincominggateway.com.

    6/18/2019 12:05 PM exchange.mydomain.local
    The e-mail address for recipient "alias1@mydomain.com" was updated to the e-mail address "user1@mydomain.com". The message is in the process of being delivered.

    6/18/2019 12:05 PM exchange.mydomain.local
    The message has been transferred from exchange.mydomain.local to EXCHANGE.Mydomain.local.
    Delivered
    6/18/2019 12:05 PM exchange.mydomain.local
    The message was successfully delivered.

  • Hi KenLiuAU,

    It seems everything is normal. 

    If the sender removes the cache of this user, and input the email address (alias1@domain.com) manually to test again. Does the same issue occur?

  • Hi Niko,

    We cannot contact those email senders as there are too many. I just wonder if there is anyway for me to check the queued emails and deliver them?

    Thanks,

    Ken

  • Hi Ken,

    You can try to remove X400 email address and check if any helps.
