Connect to an exchange server in C#

hello,

I am writing an app (possibly a windows service) that will connect to an exchange server and check for emails. Ihave been advised they do not support POP3. When an email is received the text of the email (not attachments) will be saved in a table in an oracle database. I am going to write this application in c# and .net 3.5.

Can anyone advise how difficult this task would be?

Can you also give some ideas on starting points of what to look at? eg is Webdav the right approach to use. Any links to tutorials or code samples would be appreaciated
