[python-win32] pywintypes.com_error: (-2147467259, 'Unspecified error', None, None)

[Blair, Colin S]

Hi Tim,

I have figured out the source of this error. We are running into issues with the comObjectModelGaurd. Our group policy recently changed to disallow programatic access to protected mailItem objects.

Modifying Outlook Users Trust settings or the registry will fix the problem.

R,
C. Blair

Thank for the response.

I have tried using the static proxy. The same error occurs.

I have also tried adding  DISP_E_EXCEPTION to the ERRORS_BAD_CONTEXT list in dynamic.py

Same result.

That's 0x80004005, which for MAPI is MAPI_E_CALL_FAILED.  Very generic.

Have you run gentypes.py on Outlook?  Perhaps you should try to generate
a static proxy:
    ol = win32com.client.gencache.EnsureDispatch("Outlook.Application")
