How to save HTML email as an outlook file using Python?

问题

Someone created a nice email template in outlook and sent it to me for automation.

I opened the email in HTML, and used that HTML to recreate the exact email images, formatting and all.

I can send this email out just fine, but I was then asked if I could save all the email files in a folder so that one could click on it and have it open up in their outlook (a .msg file).

I can save my email as an .mht and .elm file, but neither will open in outlook.

Seemed like an easy request...

  msgRoot = MIMEMultipart('related')...
  ...      
  ...
  msgAlternative = MIMEMultipart('alternative')
  msgRoot.attach(msgAlternative)

  msgText = MIMEText('no alternative text version')
  msgAlternative.attach(msgText)


  msgText = MIMEText("""
  ...
  ...#too much going on here to paste. formatting and attaching images.
  ...

The part where I can successfully save this as .mht file:

  with open("C:/LOCAL/test/"+var+'.mht', 'w+') as out:
        gen = email.generator.Generator(out)
        gen.flatten(msgRoot)

Is there an easy way to just save this as the .msg file so that it opens in the client? Like a preloaded email file. You open it, it's addressed etc... just need to hit send.

Work with SaveAs Method [MSDN] with OlSaveAsType to get the correct file format

Example

import win32com.client

Outlook = win32com.client.Dispatch("Outlook.Application")
olNs = Outlook.GetNamespace("MAPI")
Inbox = olNs.GetDefaultFolder(win32com.client.constants.olFolderInbox)
SubFolder = Inbox.Folders["folder name"]

for Item in SubFolder.Items:

    try:
        Item.SaveAs("D:\\Temp\\email.msg", 3)  # OlSaveAsType 3
    except Exception as e:
        print(e)
