Execute python script from VB6 to display Outlook Window

[wojtek.dominicana at gmail.com]

I have to prepare e-mail in python (e-mail address, body html, attachments etc.) and show Outlook window for user who will check everything and correct if necessary and will be able to send it.
My script work well :


o = win32com.client.Dispatch("Outlook.Application")
Msg = o.CreateItem(0)
Msg.To = "aa at gmail.com"
Msg.CC = ""
Msg.Subject = "The random subject"
Msg.HtmlBody = "<h1>content of e-mail</h1>"
Msg.Attachments.Add(attachment1)
Msg.Display()

This script work well but I have some problem with my Outlook 2019 or Command window (Win 10, 64). When Outlook is closed i can call my script using Shell() or ShellExecute() and everything is ok but when MS Outlook is open my script doesnt work. I use the same  Shell() or ShellExecute() function and still does not work although windows executing this script. It stops in the loine "win32com.client.Dispatch("Outlook.Application")". I tried many tricks and I gave up. The most important is that when I use windows command line and run my script manyally (python sendoutlookmail.py) everything works well regardless of state of Outlook (open or closed).
I think there is a different between calling script via Shell() function and run it directly from command line.
I tried of course solution as follows:

Set obj = CreateObject("WScript.Shell")
obj.Run sPythonFile 

but its the same situation. I createt bat file and I execute this bat file which has inside commant to execute my python script.

I have no idea how to run python script on my system that works the same as I call it directly from windows command line.
