 <p>I've spend many hours on that subject, one (working) thing I've found is this: <a href="https://github.com/jgallen23/OWAParser" rel="nofollow">https://github.com/jgallen23/OWAParser</a></p> <p>My problem was, after testing many times with my company's Exchange server they've locked my account. And even thought it works, after changing something small in the server configuration it will stop working, and that wasn't an option for me.</p> <p>Hope this helps you! :-)</p>
