Yes. So the way it would work is: - You use our sign in with google provider - You need to implement custom sign in with outlook provider (the link i shared previously shows you how to add a custom third party provider using our node SDK) - Post our new release (2-3 days from now), you would need to override the sign up / in API in the backend to add a check for the email being used - if it's @gmail.com or @outlook.com / @hotmail.com, then return an error that is showed on the frontend to the user. All the above can be done within a span on a few hours..
