You have to enable SMTP login for the O365 mail box or user in the admin settings

Go to Mail Settings

Turn On Authenticated SMTP

once that is done use

var transport = nodemailer.createTransport({
    service: "Outlook365",
    auth: {
      user: 'O365email',
      pass: 'O365password'
    }, 

  });
  var mailOptions = {
   from: 'o365email',
    to: 'exaple@gmail.com', // list of receivers
    subject: "Password reset requested for your account", // Subject line
    text: 'reset password',
    html: "<h1>Mail Testing</h1>" // html body
  };
  transport.sendMail(mailOptions, function(error, response){
    if(error){
      resp.status(500);
     resp.send(error);
    }else{
        resp.send({message:'done'});
    }

    });
