Python and MAPI

[Michel Orengo]

As I told you, I am still a beginner wrt MAPI. It appears that my code worked but not always! In fact, I ran myself into several problems I don't understand. The strangest one is that
some code run in Interactive window, but will not run otherwise!
Moreover, I am using the lotus cc-mail version of MAPI. You are using the one provided by Outlook.

In fact, you are lucky because your version is 1.2
I know that because I have access to the MSDN Library, and that's where you can find all the command/properties of objects of the CDO (Collaboration Data Object) the OLE wrapping of
the MAPI.

If you do not have access to the MSDN Library, you can use a COM browser: it will give you the properties/methods of the objects.
Another solution is to make Python aware of the CDO object by using makepy (see QuickStartClientCom.html)
In the file generated by makepy, you will find all the classes and attributes.

What you want to do though should be not very complex. Here is a sample code (I didn't test it!), just to provide some idea:

session = win32com.client.Dispatch("MAPI.Session")
session.Logon("MS Exchange Settings")
inbox = session.Inbox
collmsg = inbox.Messages
msg = collmsg.GetFirst()
while msg:
    print "subject: ", msg.subject
    msg = collmsg.GetNext()
session.Logoff()

Note that you can also take a look at testExchange.py under the 'test' directory.

Hope this help.
