Accessing Internet Headers

I am trying to write a c# program to access Outlook internet headers for
messages in a public folder.

When I look at these messages in Outlook, and select View/Options, there is
information in the Internet Headers scrollbox.

BUT -- when i run the Visual Basic code ( so far this is the only documented
method I have found, so I'm converting it to c# ) found here:

http://support.microsoft.com/?kbid=194870

It throws an error saying the MAPI_E_NOT_FOUND, i.e., the property doesn't
exist.

YET -- this code works on other mail in my Inbox.

Other articles tell me that the Outlook.MailItem does not contain access to
the Internet Headers so I am using the MAPI object in CDO -- but, as I said,
some emails do not allow the headers to display.


Since I can see the headers in Outlook, shouldn't the Outlook Object Model
allow me to access them ?

PR_TRANSPORT_MESSAGE_HEADERS is only available on the messages received from
the internet. Look at the same message using MdbView or OutlookSpy, do you
see this property?
