Hi,
- I suppose you should first check if your heap is still ok - perhaps
your usage of that specific DLL caused heap corruption. Then the py-API
screwed up. You should try the following standard heap check from win32
(<crtdbg.h>, _DEBUG versions)
_CrtCheckMemory() // to check all of the heap
_CrtIsValidPointer(..) // to check a specific memory region for r/w
doing _CrtCheckMemory() before and after a call can reveal alot.
- It is very important to use the same runtime library in your projects,
this is another common cause for failure.
- MAPI is a COM library. You might try this straight c++ wrapper class
first and see if the simplest example works for you:

aswell try the more simplistic CMC Common messaging calls first
(Platform SDK).
Sorry for being _UnPythonic();
