Unable to connect to SMTP server - php

Question

I have a server with mail support, say example.com. I configured the server and added MX records via cpanel, so that I can receive and send mails via outlook.com with address myaddr#example.com. The MX records are got from domains.live.com.
Now I need to send mail programmatically using PHP using SMTP. I tried PHPmailer using the following script. But it is showing the error
Mailer Error: SMTP Connect() failed.
(But I can send and receive emails via outlook.com using myaddr#example.com)
$body = $_POST['message'];
$to = "support#example.org";
$from = 'fromAddress#gmail.com';
$fName = 'first name';
$lName = 'last name';
$subject = 'my subject';
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';
// $body = eregi_replace("[\]",'',$body);
$mail->Host = "mail.example.org"; // SMTP server example
$mail->SMTPDebug = 0; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 25; // set the SMTP port for the GMAIL server
$mail->Username = "myaddr#example.org"; // SMTP account username example
$mail->Password = "password";
$mail->SetFrom($from, $fName.' '.$lName);
$mail->Subject = $subject;
$mail->AddAddress($to, "Support Team");
$mail->MsgHTML($body);
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}
How can I resolve the issue.

Answer 1

Finally I just solved the issue by replacing some of the settings as below and it worked :).
$mail->Host = "smtp-mail.outlook.com"; // SMTP server example
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
