Mailbox syncronizationn creating folders "CrmOrgMailboxPrefix" in Outlook

Posted on by CU22100956-0 31

Hi ,

We’re running into a strange issue with one specific user whose mailbox is synchronized with Dynamics 365. As soon as we enable server-side synchronization for this user, new folders "CrmOrgMailboxPrefix" begin to appear automatically in Outlook. These folders are created without any action from the user.

  • Outlook folders are being created automatically for one specific user
  • This only happens when the user’s mailbox is synced with Dynamics 365 (server-side sync).
  • The folder creation stops once we disable the mailbox sync
  • No manual action or rules on the Outlook side seem to be triggering this.

What we have tried so far:

  • Disabled the user’s mailbox sync in Dynamics 365 → folder creation stopped
  • Re-enabled mailbox sync → folder creation started again.
  • Confirmed the user has no Outlook rules that could be generating folders.
  • Checked Dynamics 365 tracking settings (no folder tracking) → nothing unusual.

Has anyone encountered this before or knows what might be causing it?

 

Thank you in advance!

    Can you please check what folder tracking rule is set on user mailbox, that setting only can create folder like this , remove this and check.
