Office365 via GoDaddy SMTP does not work

Question

I'm using PHPMailer and have tried others but this simply does not work. I keep getting an error that the server keeps denying me access. Here is the example code used:

<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3;                               // Enable verbose debug output
$mail->isSMTP();                                      // Set mailer to use    SMTP
$mail->Host = 'smtp.office365.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP   authentication
$mail->Username = '[email protected]';                 // SMTP username
$mail->Password = 'xxx';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to

$mail->setFrom('[email protected]', 'Mailer');
$mail->addAddress('[email protected]', 'Joe User');     // Add a recipient
$mail->addReplyTo('[email protected]', 'Information');
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

I'm using the same settings as shown in their official documentation: https://support.office.com/en-gb/article/POP-and-IMAP-settings-for-Outlook-Office-365-for-business-7fc677eb-2491-4cbc-8153-8e7113525f6c

What seems to be an issue? I have checked online in a number of posts but nothing seems to be working. Any ideas?

Search before you post. This is a well-known problem, covered in the PHPMailer docs and in countless questions on here: GoDaddy blocks outbound SMTP except via their own servers. — Synchro
of course i searched beforehand. Nothing seems to work even using their own servers. Do you have example code for the php above that would work and have tested it yourself? — user6934446
This is nothing to do with your Office365 settings. It's GoDaddy that's the problem. I suggest you read their docs. To be clear, the code you have posted will work fine on an ISP that does not block outbound SMTP. — Synchro

For GoDaddy Office365 accounts you must use the GoDaddy secure SMTP server: smtpout.secureserver.net
