Restrict senders to distribution group AADC

 DirSync syncs the following AD attributes that control who can and cannot send to a DL:

  • AuthOrig (Authorized Originators: Only these Users can send to the DL)
  • UnauthOrig (Unauthorized Originators: Anyone BUT these users can send to the DL)

Look under attribute editor for the user you want to send to and add the distinguished name.


Alternatively you can set it with powershell

Set-ADGroup -Identity “<group name or distinguished name>” -Add @{authOrig=@(‘CN=<Name>,OU=<OU>,OU=<OU>,OU=<OU>,DC=<DC>,DC=local’)}
