PHPMailer Authentication unsuccessful

When I try to use PHPMailer on windows server 2012 at work to send report emails using SMTP I got Authentication unsuccessful error.

I'm using server administrator account on domain.

I'm very sure of the correction of the password.

check the code below:

require '../PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';
$mail->Host = 'mail.example.com';
$mail->Port = 25;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "[email protected]";
$mail->Password = "yourpassword";
$mail->setFrom('[email protected]', 'First Last');
$mail->addAddress('[email protected]', 'John Doe');
$mail->Subject = 'PHPMailer SMTP options test';
$mail->msgHTML($html_message);

I got the below response:

Problem Solved by changing $mail->SMTPAuth = true; to False.

$mail->SMTPAuth = False;
