I was trying to download attachments from outlook which satisfy a particular subject but i got an exception that have no idea how to correct my code from below is my code:

import win32com.client
import os
get_path = os.getcwd()
outlook = win32com.client.Dispatch("Outlook.Application").GetNameSpace("MAPI")
inbox = outlook.GetDefaultFolder(6)
messages = inbox.Items
message2 = messages.GetLast()
subject = message2.Subject
body = message2.body
sender = message2.Sender
attachments = message2.Attachments
for m in messages:
    if m.Subject == "Test Mail":
        for x in message2.Attachments:
            x.SaveASFile(os.path.join(get_path,x.FileName))

As the traceback shows, the error is at the line where you define outlook . Actually, there is no cap S in GetNamespace so replace this line by:

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

but other errors occur, at the line where body is defined, a cap is mandatory for the attribute, such as body = message2.Body , and another cap issue in x.SaveASFile , it should be x.SaveAsFile

Finally, I'm not sure that your code will do what you describe as you try to download the attachments of message2 , being your last message, while you iterate through messages , I don't see the point then.

Let me know if you need more help or if I misunderstood your problem.
