Hi,

1: I don't know much about Windows APIs, but am currently reading the
"Windows Internals" book. Got this idea from it:

Go to http://www.microsoft.com/technet/sysinternals/default.mspx
and check out the SysInternals utilities there. The book says that you
can use some of them to "spy" on what an app is doing - what registry
keys it is reading/writing, lots of other OS-level calls it makes as
it runs. Digging around and using some of these utilities to check out
what an Office app does when you use it to send mail, might help you
figure out a way to do what you want.

2. Try looking for registry entries specific to Office Apps, and look
under those subtrees for likely email-related entries to modify (if
you haven't tried that already). I guess you already know that
fiddling with the registry can be risky and can crash your system, so
take backups, etc.

Using COM via Python may also help - again, some digging required. You
probably already have the PyWin32 Python extensions for Windows COM
(earlier called win32all - see http://wiki.python.org/moin/Win32All) -
if not, its available here:
