I am really busy with other projects including getting my Exchange 2013 MCSE so I really want to make an article on Lync 2013 and Exchange OWA integration. I have set it up so many times, I thought I had covered it. Since I am short on time, I looked for a reference and I found one that is as good as I would have made. Kudos to Mchahla on wordpress. I hope you don’t mind if I link to your post. A very good article with screenshots. Thank you!
