I am having the same error! And can`t find any solution online. I even tried Nodemailer lib with no success and same issue occurred.

Any suggestions ?

Can you add @outlook.com in the user section ?

outlook dropped normal smtp auth, now we should must use Oauth2, this library can not connect to outlook directly now
