<?php

  require_once '../plugin/swift/lib/swift_required.php';

  // Create the Transport
  $transport = Swift_SmtpTransport::newInstance('pod51003.outlook.com',587,'tls')
    ->setUsername('user@connect.polyu.hk')
    ->setPassword('pw')
    ;

  // Create the Mailer using your created Transport
  $mailer = Swift_Mailer::newInstance($transport);

  // Create a message
  $message = Swift_Message::newInstance('Wonderful Subject')
    ->setFrom(array('john@doe.com' => 'John Doe'))
    ->setTo(array('foodil@hotmail.com', 'foodil@yahoo.com.hk' => 'A name'))
    ->setBody('Here is the message itself')
    ;

  // Send the message
  $result = $mailer->send($message);

  printf("Sent %d messages\n", $result);

?>

It turned out:

Actually I follow the tutorial straightly, so is that any thing I omitted in my code? The SMTP server information is valid.

External SMTP setting:
Server name: pod51003.outlook.com – you can also see the note below on how to determine the server name
Port: 587
Encryption method: TLS

after adding the line: there is another error:

Warning: stream_socket_enable_crypto() [streams.crypto]: this stream does not support SSL/crypto in C:\xampp\htdocs\fyp\plugin\swift\lib\classes\Swift\Transport\StreamBuffer.php on line 102

    Try adding this line here as shown:

    // Create the Transport
$transport = Swift_SmtpTransport::newInstance('pod51003.outlook.com',587,'tls')
->setUsername('user@connect.polyu.hk')
->setPassword('pw')
;

// ADD THIS LINE
$transport->setLocalDomain('[127.0.0.1]');

// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);

    I’m guessing your SMTP server doesn’t like/understand IPv6, based on the response you are getting to the HELO command.
