Cause

  • Windows Azure Active Directory Synchronization learns about the existing Active Directory forest's domain and Organizational Unit structure during its initial Full Sync cycle, where all of the FIM run profiles are of type Full
  • After the first Full Sync has completed, Windows Azure Active Directory Synchronization begins performing Delta Sync cycles on a 3-hour interval from that point forward
  • New Organizational Units will be realized during Delta Sync cycles, but changes in the Distinguished Name of an existing Organizational Unit (i.e. - the Organizational Unit has been moved in Active Directory to another location) are not synchronized correctly during a Delta Sync cycle, and will cause the errors shown in the Symptom section of this article.
  • In order for Windows Azure Active Directory Synchronization to succeed future Delta Sync cycles, a Full Sync cycle must occur first

Resolution

On the Windows Azure Active Directory Synchronization server:

  1. Start, Run, RegEdit.exe
  2. Drill down to: HKLM\SOFTWARE\Microsoft\MSOLCoExistence
  3. Double-click the FullSyncNeeded value
  4. Set FullSyncNeeded to 1 and click OK
  5. Close RegEdit
  6. Open PowerShell, and then type Import-Module DirSync
  7. Type Start-OnlineCoexistenceSync, and then press Enter
  8. Launch the FIM console (miisclient.exe)
  9. Select the Operations tab
  10. Watch each of the ‘Full’ run profiles execute for SourceAD and TargetWebService
  11. Once TargetWebService Export has completed, you should then see a Delta Sync operation begin within 3 hours, and the Discovery Errors for the Organizational Unit(s) in question should now be resolved
