Hello Matt,
This will work in a windows application as well, as long as you have OWA (Outlook Web Access) available on your exchange.
If you need, you can also have a look at the using Microsoft Office PIAs (Primary Interop Assemblies) or develop a custom library. The other alternative is getting a 3rd party solution from www.aspose.com or www.chilkatsoft.com
Here is another option: http://dotnetjunkies.com/Tutorial/2E1EEEAF-C78A-4A38-A830-AC204B12DF83.dcik
If you can give some more details regarding your solution, and your exchange setup, i.e. is it a local exchange, hosted exchange etc and how you envisioned on implementing the solution and what the requirements are.
