Using IMAP To Access Calendar on Exchange Server

[nh_capricorn]

Hi,

I am fairly new to .NET (coming from a Java background) and I am trying to
port an application that I originally wrote in Java, to .NET / C#. My problem
is that I cannot find a C# analog for the javax.mail library. My original
program used this to access the calendar on Exchange, via IMAP and retrieve
appointments.

I have no idea how to do this. Any help, advice, or even general guidelines
would be much appreciated. I would be very surprised if what I wanted to do
wasn't possible.

Here's a snippet of the original Java code. As you can see, it should be
fairly easy to do:

public void checkCal() {

Folder folder = null;
Store store = null;


// 1. Open the mailbox and retrieve messages
System.out.prin tln("user: " + user + "Password: " + passwd);
URLName url = new URLName(protoco l, imapHost, -1, mbox, user, passwd);
Session session = Session.getDefa ultInstance(pro ps, null);
session.setDebu g(false);
store = session.getStor e(url);
store.connect() ; //this is a resource that needs to be cleaned up!
folder = store.getDefaul tFolder();
folder = folder.getFolde r(mbox);
folder.open(Fol der.READ_WRITE) ;
int totalMessages = folder.getMessa geCount();

System.out.prin tln("Num Messages=" + totalMessages);
Message[] msgs = folder.getMessa ges();
FetchProfile fp = new FetchProfile();
fp.add(FetchPro file.Item.ENVEL OPE);
folder.fetch(ms gs, fp);
}

Oops.... what I meant to say was that I couldn't find a .NET analog for
javax.mail.... I am writing the program in C#

Wow, the Java code looks quite elegant! I'd be interested to see side by
side compare with .NET

Exchange traditionally used MAPI, and if you do a search on "CDO" you'll
find a lot of information about the object model and what you can do
with it - including managing calendars, but I'm not sure about IMAP.
You're talking "open-standards" here, which don't always sit too well in
the Microsoft world!

One thing I did notice that's funny - the latest Exchange SDK states
that it's "not compatible with .NET" and guess what... you have to use
COM interop! I guess .NET doesn't "rock" quite as hard as we were lead
to believe in the latest press release.
