Well, here is an extract of the file produced by makepy (under gen_py):
- BTW, I selected the "OLE/Messaging 1.0 Object Library" not sure what is the
msoutlk85.olb.-

class Message(DispatchBaseClass):

This give you the methods (Send, Delete, Update...) + attributes (Application,
Attachements,...) [and actually some you can get and/or put]
so you in my previous example I used  "msg.subject", you can also get msg.text
to get the body of the message.
What is less obvious is thing such as Recipients, because Recipients is a
collection of objects (ie Recipient), but you can find the description of the
class Recipient in the same .py generated by makepy.

Or again look at CDO (under "Platform SDK, Database and Messaging Services") in
MSDN Library.
