win32com.client.Dispatch(“Outlook.Application”) error pywintypes.com_error: (-2147221005, 'Invalid class string', None, None)

Question

I am on windows 7 and I have windows live installed. Now when I am trying to run following code

import win32com.client
win32com.client.Dispatch(\"Outlook.Applica         


        

Answer 1

I was having a similar error. Have you tried running makepy.py from win32com's folder to create entries for the different COMobject's you are using? Basically, win32com just treats all of applications you interact with as default COMobjects until you let it learn about the programs installed on your computer. You'll have to run makepy.py for each program you want to control with it.

After I ran it, I gained access to much more control for Outlook. It has opened other errors that I am working on correcting.

Also, if you take your comobject (comboject = win32com.client.Dispatch("Outlook.Application")) and look at comboject._prop_map_get_.keys() you'll see all the things you can use for that program.

Answer 2

This is an indication that Outlook is not installed. "windows live" or "outlook.com" would not help you.
