Accessing Calendar (Outlook for Exchange) via IMAP / C#

Question

Hi, I need to be able to access the calendar in Outlook for Exchange, and retrieve appointments. The problem is that I cannot find any examples of how to do this. Ideally, I would like to be able to search for a particular type of appointment, such as a sales appointment. My questions: How to I log in to the server via IMAP? How do I access the calendar? How do I retrieve the appointments. How do I retrieve a particular type of appointment (such as a sales appointment). Is this possible? Any help, advice, or (especially) examples would be greatly appreciated! sianan
