ics file not reflected in outlook calendar

I am trying to send an meeting invite from a php code, I am sending the meeting invite through an ics file. However the ics file is coming in as attachment in Gmail but not being reflected in Ms Outlook.

This is the following File Format that I have:

I am not able to figure out where is the problem. This is my Php code

<?php
$domain = 'xyz.com';

//Create Email Headers
$mime_boundary = "----Meeting Booking----".MD5(TIME());

$headers = "From: ".$from_name." <".$from_address.">\n";
$headers .= "Reply-To: ".$from_name." <".$from_address.">\n";
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\n";
$headers .= "Content-class: urn:content-classes:calendarmessage\n";

//Create Email Body (HTML)
$message = "--$mime_boundary\r\n";
$message .= "Content-Type: text/html; charset=UTF-8\n";
$message .= "Content-Transfer-Encoding: 8bit\n\n";
$message .= "<html>\n";
$message .= "<body>\n";
$message .= '<p>Dear '.$to_name.',</p>';
$message .= '<p>'.$description.'</p>';
$message .= "</body>\n";
$message .= "</html>\n";
$message .= "--$mime_boundary\r\n";

$ical =

There's some great investigation of this problem in this open issue in PHPMailer. Though it's not a problem of PHPMailer's making (it's Outlook's fault), there's no easy way to build the workaround in PHPMailer - you may be better off usig a different system to build your MIME structure, such as Zend_MIME.

Outlook requires that the text/calendar part must be the one and only MIME part.

HTML body can be set as part of VCALENDAR.
