Brett Lindsey You should block legacy authentication anyway with conditional access. With that you get rid of most 3rd party apps. As far as I know, only the native iOS email application supports modern authentication.
Two policies with block as action control, one for other clients and one for active sync under client apps.
In combination with approved client app cond acc. and eventually App Protection policy you should be able to force the users to use Outlook
