I am testing OAuth 2.0 integration for SMTP and POP3 in a desktop application. The app has a service component that sends and receives emails from a single account in the background.

I set up a @outlook.com online account to test with. The POP3 login and receiving is working, but for some reason the mail component I'm using doesn't allow you to specify the POP authentication method. So I suspect it's defaulting to Basic Auth and giving me a false positive.

Is there any way to make it so 3rd party applications can only authenticate the outlook account with OAuth? I believe gmail has a setting like this where you can "disallow less secure apps".

I registered for an Office 365 trial using the outlook account - not sure if that gives me more options for this type of thing.

Any info or suggestions would be much appreciated!
