Our Node.js program used to use Outlook email to send emails without any issues, and provided user/password authentication using Basic. However, the Basic authentication method has recently been abandoned by Outlook mailbox, so now email sending has failed. I checked the information and it says that oauth2 authentication needs to be enabled, May I ask how to fix this issue and what tasks do I need to do? Using Outlook can successfully send emails.
