issues between exchange and 365 for one user RRS feed

  • Question

  • hybrid setup, exchange 2013, and 365.

    all users are on 365, copiers and couple of servers send email to 365 via exchange relay.

    having an issue with single new user.  report emailed from server, goes to exchange 2013 relay connector, then to 365.

    emailed report has 3 people copied on it, the two preexisting users received the email, the new user did not.

    I ran PS commands on my exchange server for message trace, and it shows the email being sent out to all 3 users.

    nothing appears in quarantine on 365.

    message trace on 365 from the report email to the new user returns nothing though,  

    what am I missing?  its almost like 365 is saying "nope" for these emails to this one person, but no recording the nope anywhere.

    is there another place to look?

  • Hi captainjamestkirk,

    Do you mean that your application relay email from Exchange on-premises to 3 Exchange online mailboxes, however only two of them receive this email?

    If so, I would suggest you have a check:

    1. Check this email from the user who received the email, whether the new created user show in the ”To“ list. If this new created user doesn't listed in the "To" list, it mean this mailbox is removed before this email come to Exchange online.

    2. Try to send email from an on-premises mailbox to your new Exchange online mailboxes, check whether is it could send successfully.

    If this new created show in the "To" list and you could send email to this mailbox directly, you could check the "message ID" for this missing email from Get-MessageTrace command:

    Get-MessageTrace -SenderAddress john@contoso.com -StartDate 06/13/2018 -EndDate 06/15/2018 | ft Received,SenderAddress,RecipientAddress,Subject,MessageTraceID

    Then you can check the detail information about this message with Get-MessageTraceDetail command, you could see whether there exist this mailbox in the mail flow:

    Get-MessageTrace -MessageTraceId 2bbad36aa4674c7ba82f4b307fff549f | Get-MessageTraceDetail

  • the new users email address does NOT show up in the TO, and if I do message trace in 365, I see the email going to the other uses, but new user does not show up.

    so it DOES look like the new user is being stripped out of the email before it hits 365.

    how do I find out why?

    Whether there exist other email filter application tool in your organization. I think this recipient may be removed but it. Or your original email may doesn't contained in this recipient at all.
