A couple of months back, a gentleman who has now become a friend and business partner, came to me and asked me if there was any way to get at all the calendar items in his sales organization’s calendars with the intention of integrating it with his Progress OpenEdge CRM system. Jim is using Exchange 2007 for his e-mail and calendaring solutions.
I was aware that Microsoft had released a new API for Exchange in Exchange 2007 called Exchange Web Services (EWS), and so I said that I needed to do a little research on the API, but I was pretty sure that it was possible. Sure enough, MSDN has some documentation of the API and Microsoft is touting it as the replacement for all APIs that communicate with Exchange. Web Services – how hard can it be?

It’s been a really busy week since I posted my first post on Exchange Web Services. I have learned a lot in that short period of time that I want to share with you. Whether you are an OpenEdge, Java or .NET developer, I think this post is going to have some information for all of you.
In my first post, I told you about the background story – I need to enable an OpenEdge CRM application to create, modify and delete calendar and task items in Microsoft Exchange. I also need Exchange to let me know any time a calendar or task item is changed so that I can update the OpenEdge database accordingly. Simple use cases.
When I left off last week, my next step was to get Exchange subscriptions working, and, boy, what a trip that has been.
