In my web app, I want to use Azure AD to authenticate users. The problem is that I can authenticate users with an address like me@mywebsite.onmicrosoft.com but I can not authenticate a user such as me@outlook.com. When I add a user with outlook.com, they can't login and instead receive an error.
I don't want to use the onmicrosoft.com addresses as it requires more setup and it's one more username and password that people need to remember. If they can use their existing Microsoft credentials, it's better for everyone. Does anyone know how to configure this?
