Reading outlook appointment replies with PHP

I have a page where the admins create events for a committee and the calendar notification is sent out to all of the member of the given committee.

What I want to be able to do is somehow retrieve the reply, whether it was accepted, tentative, or declined, and display the list of respon开发者_开发百科ses along with the event info.

The event creator will be setup to use an email address with the sole purpose of creating the events.

I am able to connect to the inbox and read emails, i can read the initial event creation just fine, like its an ics file, but when i try to read the response from someone all i get is garbage:

Start with PHP IMAP to check the box for new messages and sort out the ones you want to parse. Beyond that, you'll need to identify the structure of the Outlook reply messages, and start parsing out the information you want. preg_match() will be your friend to extract text there, but without seeing examples of the messages we won't be able to help too much more.

The mailparse library will help to deconstruct the MIME messages, if simply retrieving the message body if imap_fetchbody() isn't enough.
