A. This situation happens when you completely remove a server from the site before notice of the server’s event folder being deleted is replicated throughout the site—all the other servers still think the folder is there, and the original server is no longer around to tell them otherwise. The fix for this problem is pretty straightforward:

  1. Log on to the problem server using your Exchange Server service account.
  2. Stop the Microsoft Exchange Event Service.
  3. Run \exchsrvr\bin\events.exe with the /c:serverName switch. This switch tells the Event Service to clean up its folder list; after you run the command, the Events Root folder will no longer have two folders.
  4. Restart the Event Service. You might have to press F5 to force Microsoft Exchange Administrator to update its folder list.
