Recently I was involved in a project to connect from one of our company product to MS Exchange server. This was not as easy as I though it would be. There were lot of articles in net, however nothing was there with the end to end information I needed. Hence after I finally completed the project I created a blogspot dedicated to connecting to MS Exchange from multiple clients. I have done the Java connectivity via EWS and published. I will be updating the blog with a WEBDAV- Java version as well as a Python version soon.

Hope this helps all of you
