Roel80 Thanks for the reply. It is good to know we are not alone in this.

We opened a ticket with Microsoft, and after mover 2 months, we still do not have a solution. Our only temporary solution is to delete the faulty record on the user's mailbox using MFCMAPI. This seems to work for a few weeks or more, then the issue reappears.

Microsoft suggested starting Outlook with the command Outlook.exe /CleanConvOnGoingActions as referenced here Messages in an e-mail thread are automatically moved to the Deleted Items folder - Microsoft Support. This was after informing them the issue referenced in the article did not match ours.

We just got a new ticket for the same issue on a mailbox we ran that command on....I'll post an update once Microsoft responds.

  USC_IT Thanks for your reply.
  We also received today this solution:
  Configure user's profile in outlook in online mode.
  
  2. Install MFCMAPI Tool
  3. Go to “Tools” > “Options”.
  4. Make sure that “Use the MDB_ONLINE flag when calling OpenMsgStore”
  5. And “Use the MAPI_NO_CACHE flag when calling OpenEntry” are checked. Click “OK”.
  6. Click on “Session” > “Logon”.
  7. Choose the Outlook profile
  8. Double click the profile
  9. Expand “Root Container” > Scroll down > Expand “Top Information Store”.
  10. Select Inbox
  11. Locate PR_ADDITIONAL_REN_ENTRYIDS_EX attribute in Inbox folder
  12. Copy the value in a txt file and save it in the machine.
  13. Remove the value and change it for this value:

  check if the issue persists.
  
  So this worked for a few weeks? I will try this also and let you know.
  Keep me posted 😉

    Roel80 Nice. That is different from what we were doing. We have been deleting the PR_ADDITIONAL_REN_ENTRYIDS_EX attribute and letting Outlook rebuild it. After some time, the issue re-appears.
    
    Perhaps replacing it with that data will help. Fingers crossed!
