If you are using 2-step authentication, you will need to create an app password.

Login to your Microsoft account.

Security
Advanced security options
App passwords
Create a new app password

transp: {
    host: smtp.office365.com,
    port: 587,
    secure: false,
    auth: {
        user: 'user@email.com',
        pass: 'AppPass'
    }
}

I can see in your code that you are using secure: false field.
Instead of secure: false field you can change into secureConnection: false.

var userTransporter = nodemailer.createTransport({
  host: 'smtp.office365.com',
  port: 587,     // secure SMTP
  secureConnection: false,
  auth: {
    user:SENDER_EMAIL,
    pass: SENDER_APP_PASSWORD,
  }
});

Make sure to check in your package.json file the "nodemailer" : "*" dependency is added, if not make sure to add it.

I tried with secureConnection: false too. But error is still same — Muskan Bansal, May 16 '22 at 06:37
