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

Question

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.

Does this answer your question? Saving to .msg file in Python, or alternatively, sending mail to the file system — AMC

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)
