title: Can't setup nodemailer with outlook
body: <p>I'm using "nodemailer": "^4.6.8" and "nodemailer-smtp-transport": "^2.7.4". I am developing contact form on my site and trying to send form mail over the outlook. From some examples over the internet I tried this code, where xxxxx@hotmail.com is my email address:</p>
  
  <pre><code>  const transport = nodemailer.createTransport({
          service: "Hotmail",
          auth: {
              user: "xxxxx@hotmail.com",
              pass: "xxxxxxxx"
          }
      });
  
      var mailOptions = {
          from: 'somemail@mail.com', // sender address
          to: 'xxxxx@hotmail.com', // my mail
          subject: `message subject`, // Subject line
          text: 'plain text', // plain text body
          // html: params.html, // html body
          // attachments: params.attachments
      };
  
      transport.sendMail(mailOptions, (error, info) =&gt; {
          if (error) {
              return console.log('Error while sending mail: ' + error);
          } else {
              console.log('Message sent: %s', info.messageId);
          }
          transport.close(); // shut down the connection pool, no more messages.
      });
  </code></pre>
  
  <p>But this code gives in console error:</p>
