After checking similar posts online, still couldn't figure out the issue. I am trying to send email through nodemailer by using my outlook business email. I am getting this error message that I couldn't fix.

Here is error message:

Error: Invalid login: 451 4.7.0 Temporary server error. Please try again later. PRX4  [BY3PR10CA0026.namprd10.prod.outlook.com]

Tried adding tls to { ciphers: 'SSLv3' }, didn;t work out.

Here is part of my code:

    const output = `<h3>Hello</h3>`;

    let transporter = nodemailer.createTransport({
        host: "smtp-mail.outlook.com",
        secure: false, 
        port: 587, 
        auth:{
            user:"myoutlookemail",
            pass:"mypassword"
        }
    })

    let mailOptions ={
        from:'myoutlookemail',
        to:req.body.email,
        subject:"Hello there",
        text:"Hello there",
        html:output
    }

    transporter.sendMail(mailOptions,(error,info)=>{
        if(error){
            console.log('*********ERROR IS HAPPENING*************')
            return console.log(error);
        }
        console.log('Message Sent~~~~~~~~~~~~~~~: %s',info.response);
        //console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));
    });

Try this

Edit as required


const nodemailer = require("nodemailer");

const transporter = nodemailer.createTransport({
    service: 'service_provider',
    auth: {
        user: 'email',
        pass: 'password'
    }
});

const mailOptions = {
    from: 'email',
    to: req.body.email,
    subject: 'Protocol 5416',
    text: "Anything"
};

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