CDO, MAPI, WEBDAV

[yefei]

I just came to know these three terminologies, but do not knwo how to
differentiate then.
what i want to do is quite simple, to access the calendar folder on the
exchange server using one of these three technologies. But when I check
the availability of these three in a C#.net environemnt, seems the
MSMAPI only have the message and meeting class and interface, no folder
class.
I am reading a book on CDO and MAPI which was written in 1999(quite
old). I saw some article says that MAPI is not supported by the latest
Exchange server. and hte CDO1.21 doesnot supporte remote access to the
exchange folder.
so I wonder, are there ways to do it(must have) desides webdav, which
is considered to be slow?
if somebody knows this, can just give me a brief example of the
connection(with or without ADODB?), and the class that will be used to
get the calendar folder, the meeting, the appointment items?

If you're designing a server-based application, which is what this sounds like, WebDAV is what you should use. It's the only one of the three you cited that is supported in C#.

BTW, the newsgroup for Exchange programming is microsoft.public.exchange.development. Documentation starts at http://msdn.microsoft.com/exchange/
