Problem while reading an outlook in box using python.

[venutaurus539]

Hello,
I was getting an error in Cocreate instance while trying to
access "Outlook" using python script. The python script looks like:

from win32com.client import Dispatch
session = Dispatch("MAPI.session")
session.Logon('OUTLOOK') # MAPI profile name
inbox = session.Inbox

When I tried to execute the script I got the error:

IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx,
pythoncom.IID_IDispatch)
com_error: (-2147221005, 'Invalid class string', None, None)

Can any one guide me in obtaining a solution
for this.


Thanks in advance,
Venu.

Do you have Outlook installed with the CDO components?
(I think it became an option unchecked by default
at some point).

If not, then you won't have the MAPI.Session class
registered.

As a double-check, look in the registry for:

HKEY_CLASSES_ROOT\MAPI.Session

May I know how to check whether my Outlook is installed with CDO
components?

There is no entry in my Registry Database with the name MAPI.Session.

Thank you,
Venu.

Well, that pretty much *is* the check. Get hold of your Office
install disk and do a reinstall and look out for suboptions
of Outlook saying things like "CDO" or "Collaboration Data
Objects". Tick the box and click [Install].
