This is about a process that runs as a Windows 7 service. It is a
python executable that I am trying to run as a service and when it is executed
from the commandline it runs fine. However when it runs as a local account
(which is the same user as the user that runs it from commandline) it fails
with the following error:-
(<class
'pywintypes.com<http://pywintypes.com/>_error'>, com_error(-2147024891, 'Access
is denied.', None, None)
The line where it fails is the following:-
MyConn =
win32com.client.gencache.EnsureDispatch("Outlook.Application").GetNamespace("MAPI”)
For security reasons, services in Windows run in what is called “session 0”,
which is prohibited from connecting with the desktop. The Outlook application
is a GUI application, so it cannot run in session 0.
There are a couple of alternatives. You can modify the service configuration
to allow it to interact with the desktop, or you can connect with MAPI without
going through Outlook.
