For sometime I thought that I should post a native code sample of a client code to Exchange Web Services. After all, we have used WSDL for EWS to tune wsutil.exe and test interoperability during developement of WWSAPI. I have even built a prototype but never had a chance to finish it. However, after this post on forums by steve_olivier with a sample of WWSAPI based client, I do not think there is much left for me to show in an example. Thanks Steve! If you are interested in building native code clients to EWS, check out this discussion on the forum and let me know if you have any issues. Just add your questions to the discussion on the forum or comment on this post.
