I configure everything the same as the document sent by you, however in hotmail it sends, for example, the welcome email but not the Verification email.
In some tests we did, it sends the verification message but at the wrong time.
Please try using the Test Email tool depending on the SMTP plugin you’re using, it’s also important to link your site with a trusted email service (e.g. Sendgrid, GMail…). Just installing the plugin is not enough, emails sent by WordPress (not via trusted services) are often not delivered. Also, you can try customizing the email subject and text, maybe Hotmail detects some keywords as suspicious.
