Deprecation of basic auth on microsoft exchange server

Thank you for reaching out to us. I have submitted a message to the developers to investigate further your findings.

Kind regards.

As an update to this issue, Microsoft is requiring that the connection be made using an App Password, rather than your regular Outlook login password.

This guide on their site will walk you through creating an App Password:

Just use it in place of your regular password and your SMTP connection should be good.

I hope that helps! Have a great day! ??
