Hi,
As mentioned here https://docs.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-i...

Oauth2 support for imap and smtp protocols is not supported for outlook.com customers. What does this exacly mean? What about other domains like hotmail.com, msn.com etc?
We want user to login using Oauth2, can a office365 user have outlook.com domain? how to differentiate between a office365 and non-office365 user?
