Rules saved on the Exchange server are always run before rules saved on your computer. To create or edit rules based on the Exchange server, you must have a Microsoft Exchange account managed by Microsoft Exchange Server 2010 or later. For more information, see Server-based rules versus On My Computer rules.
If you have an Exchange account, some rules that were created in Outlook for Windows or Outlook Web App may not be editable in Outlook for Mac. To edit these rules, use Outlook for Windows or Outlook Web App.
