[python-win32] MAPI with win32com

[Werner F. Bruhin]

I am trying to use MAPI to send an email using win32com, but I get the 
following exception.

from win32com.client import Dispatch
s = Dispatch("Mapi.Session")
Traceback (most recent call last):
   File "<input>", line 1, in <module>
   File "C:\Python25\lib\site-packages\win32com\client\__init__.py", 
line 95, in Dispatch
     dispatch, userName = 
dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)
   File "C:\Python25\lib\site-packages\win32com\client\dynamic.py", line 
98, in _GetGoodDispatchAndUserName
     return (_GetGoodDispatch(IDispatch, clsctx), userName)
   File "C:\Python25\lib\site-packages\win32com\client\dynamic.py", line 
78, in _GetGoodDispatch
     IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, 
pythoncom.IID_IDispatch)
com_error: (-2147221005, 'Cha\xeene de classe incorrecte', None, None)

I first tried this having Thunderbird as my MAPI client, then installed 
Windows Live Email (I want to test MAPI with one of the "newer" MS Mail 
clients) and defined it as the MAPI client (Default Programs - MAPI), 
still same result.

Any hints on what I am doing wrong here would be very much welcomed.

I am on Windows 7, Python 2.5.4, py2in32 build 210.
