Develop a windows service to process exchange inbox via MAPI

Did anyone access Exchange inbox using MAPI in a Windows service?  We have a problem to access the mailbox.  The error seems "server is not available."  What we did were
1) log in to the windows xp box using generic AD account, which is the owner of an emailbox.
2) create mail profile.  To verify the profile, the inbox can be accessed using Outlook interface.
3) exit Outlook and Outlook process.
4) run the newly-developed Windows service, which calls the profile and uses its password.
5) we got exception.

Is it something done by anyone?  Any advices for troubleshooting?

This is not a really simple issue, yet MSDN covers it. See ("How To MAPI Enable a Windows NT Service")

Thanks, jkr.  Make it even more complicated.  We developed it in C# code.  Here is a msdn blog about it.  What is it really mean?  Any further enlightenments?
Well, that only means that you risk memory leaks when using CDO. How is your MAPI interaction implemented? If that is plain MAP, that article does not apply.
