Hi everyone.

We encountered a very strange bug with exchange search.

Context:

Outlook working in on-line mode (running on terminal servers, so we can`t chnage it to cached mode due high IO)

When user get message with any attached file AND forward it, the message disappears from the search results. Outlook search showing forwarded message from "SENT" folder, but do not showing original message in "INBOX"

There is an example on sreenshot

as you can see, search showing only 3 results, while we have 4 messages (2 in inbox, 2 in sent).

OWA have same issue.

Users do not use Conversation View, as some correspondence may contain dozens of messages that are difficult to view in this form.

This problem appear after upgrading to Exchange 2019 (CU3) from 2016. Now we installed CU8, but this bug still here...

Has anyone encountered a similar bug?

    Hi ,
    Do you have this issue with forwarding emails without attachments?
    After forwarding, can you see the original mail in your mailbox?
    Only one user have this issue or all have?

    1. Please check and make sure all Exchange servers are running normal, especially the “MS search service” and “MS search host controller”.

      2.Confirm that the database where the user is located has search index enabled, and the value of IndexEnabled should be true by running: Get-mailbox <user name> | fl name,database
      Get-MailboxDatabase <db name> | fl Name,IndexEnabled

    3.Check the status of the database and content index by running below command. If ContentIndexState shows FailedAndSuspended or Failed status, try to rebuild the database content index directory.

    Get-MailboxDatabaseCopyStatus | ft Name,Status,ContentIndexState

    Without attachments search working fine, you can see it on screenshot.
    After forwarding - yes, the original message exist in inbox, but search don`t showing it.
    Only one user - no, all users, also i have tested this bug on 3 installations of Exchange Server 2019 in different Active Directory forests.

      • Service working, we tryed to restart it, but unsuccessfully
      • As i know, exchane 2019 does not have IndexEnabled attribute in mailbox database, because search engine was changed.
        P.S. Mailbox migration from one MDB to another fix issue with exsiting messages. But after migration new emails having same problem.

    Hi @MarcoMandricardo-1414 , @Antoл K
    In the past month, I have installed several Exchange 2019 CU versions that you mentioned as having issue. And many experiments have been carried out in the environment, but unfortunately we have not been able to successfully reproduce your problem. In addition, I also searched and researched cases of search problems caused by BigFunnel, but no specific solutions were found in the cases.

    Considering that the problem has already affected your actual use, in order to further investigate the root cause of the problem, it is recommended that you open a case with Microsoft for further investigation.

    If you successfully solve the problem, you can also share your solution here. This will be beneficial to other community members as well.

    I will continue to test and research to find more relevant information.
