How to send emails thru nodemailer (node.js) from outlook? SMTP Disabled

Question

Hello, I'm writing a small backend node.js application from which I'd like to send emails. I set everything up in the following fashion:&nbsp;  try {
    const transporter = nodemailer.createTransport({
      host: "smtp.office365.com",
      port: 587,
      secure: false, // STARTTLS
      auth: {
        user: "email address removed for privacy reasons",
        pass: "secret-password",
      },
    });

const mailOptions = {
      from: senderEmail,
      to: recipientEmail,
      subject: "Quote from Anonymous",
      text: JSON.stringify(storedFormData, null, 2),
    };

await transporter.sendMail(mailOptions);
    res.json({ message: "Email sent successfully." });&nbsp;However, no matter how I change the structure of the code I keep getting the following error:code: 'EAUTH',response: '535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant. Visit https://aka.ms/smtp_auth_disabled for more information. [FR2P281CA0043.DEUP281.PROD.OUTLOOK.COM 2023-09-05T20:12:25.431Z 08DBACD4F0020982]',responseCode: 535,command: 'AUTH LOGIN'So I guess my question is, how to enable SMTP for tenant?

const nodemailer = require('nodemailer');
const { ConfidentialClientApplication } = require('@azure/msal-node');

const config = {
auth: {
clientId: 'YOUR_CLIENT_ID',
authority: 'https://login.microsoftonline.com/YOUR_TENANT_ID',
clientSecret: 'YOUR_CLIENT_SECRET',
}
};

const cca = new ConfidentialClientApplication(config);

const getAccessToken = async () => {
const result = await cca.acquireTokenByClientCredential({
scopes: ['https://graph.microsoft.com/.default'],
});
return result.accessToken;
};

const sendEmail = async () => {
const accessToken = await getAccessToken();

const transporter = nodemailer.createTransport({
service: 'Outlook365',
auth: {
type: 'OAuth2',
user: 'email address removed for privacy reasons',
accessToken: accessToken,
}
});

const mailOptions = {
from: 'email address removed for privacy reasons',
to: 'email address removed for privacy reasons',
subject: 'Test Email',
text: 'Hello, this is a test email sent using Nodemailer and OAuth2!',
};

transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Email sent: ' + info.response);
});
};

sendEmail().catch(console.error);
