I am trying to set the default Email Import Folder.  There are various answers here which refer to the Admin Console > Repository Options > Settings > Outlook Import and the default email Folder Path.

This setting is missing from my 10.3.1 and 10.4 Admin Consoles.  It also does not appear on the Client > Options > Outlook settings.

Why is it missing?

Could I also have the default Attributes setting for the Default Email Folder so that I can add this to Everyone?
