I installed Azure AD Connector, followed the directions for an express install. When the sync occurred, everything was sync to include Service Accounts. All I want is active users that are in certain OU's. How do I remove what was synced and sync what I need? We have been using O365 for some time and the online account was updated (which was ok). I was reading this post https://azure.microsoft.com/en-us/documentation/articles/active-directory-aadconnectsync-configure-filtering/ but it came back with a Stopped Deletion Threashold. Did not want to proceed if it was going to delete everything fom O365.
Any help or suggestions?
