First of all, thanks for giving a self-contained code example so we know
what you're seeing. Next, by way of answering your question somewhat
indirectly, try this:

<code>
import win32com.client

app = win32com.client.gencache.EnsureDispatch("Outlook.Application")
outlook = app.GetNamespace("MAPI")

print(repr(outlook))
help(outlook)

</code>

Because I've generated a static proxy for the underlying COM objects,
you can use the standard Python introspection for a certain amount of
useful information. Generally you can see the methods with their parameters.

Also, though, instead of a generic "<COM Object>" you can see that the
"outlook" object is an instance of the _Namespace class in the Outlook
12.0 object library. Even if there was nothing else you could do through
Python itself, you can drop those terms into a search engine and come up
with something like:

Obviously you can do the same with the messages etc. so:

<code>
# carrying on from above...

inbox = outlook.GetDefaultFolder(6)
message = inbox.Items.GetLast()

print(repr(message))
help(message)

</code>

and here, the message is a MailItem instance and so we can get to here:

  http://msdn.microsoft.com/en-us/library/office/ff861252.aspx

and so on.

If you want to, you can go digging in the _prop_map_get_ attribute which
is how the Python Dispatch wrapper stores its internal mappings, but
it's a little involved if you're just hoping for a list of attribute
names (and, especially, their meanings).
