Extracting Embedded Images From Outlook Email

Question

I am using Microsoft\'s CDO (Collaboration Data Objects) to programmatically read mail from an Outlook mailbox and save embedded image attachments. I\'m trying to do this f

Answer 1

Difference in versions of OS/Outlook/CDO is what might be the source of confusion, so here are the steps to get it working on WinXP/Outlook 2007/CDO 1.21:

• install CDO 1.21
• install win32com.client
• goto C:\Python25\Lib\site-packages\win32com\client\ directory run the following:

python makepy.py

• from the list select "Microsoft CDO 1.21 Library (1.21)", click ok

C:\Python25\Lib\site-packages\win32com\client>python makepy.py
Generating to C:\Python25\lib\site-packages\win32com\gen_py\3FA7DEA7-6438-101B-ACC1-00AA00423326x0x1x33.py

Importing module

• Examining file 3FA7DEA7-6438-101B-ACC1-00AA00423326x0x1x33.py that's just been generated, will give you an idea of what classes, methods, properties and constants are available.

Now that we are done with the boring steps, here is the fun part:

import win32com.client
from win32com.client import Dispatch

session = Dispatch('MAPI.session')
session.Logon ('Outlook') # this is profile name
inbox = session.Inbox
messages = session.Inbox.Messages 
message = inbox.Messages.GetFirst()

if(message):
    attachments = message.Attachments
    for i in range(attachments.Count):
        attachment = attachments.Item(i + 1) # yep, indexes are 1 based

        filename = "c:\\tmpfile" + str(i)
        attachment.WriteToFile(FileName=filename)
session.Logoff()

Same general approach will also work if you have older version of CDO (CDO for win2k)
