Any code that you write in Outlook VBA to do this won't be translatable to an Exchange event sink, which is how you'd want to handle a public folder.
But for the VBA solution, download the Office 2003 Web Services Toolkit from http://www.microsoft.com/downloads/details.aspx?FamilyID=fa36018a-e1cf-48a3-9b35
-169d819ecf18&DisplayLang=en. This will give you the plumbing you need for the SOAP calls.
The other piece is to use the MAPIFolder.Items.ItemChange event to monitor a folder for changes. The Help topic on that event explains it well. YOu can also see an example of the similar ItemAdd event at http://www.outlookcode.com/d/code/zaphtml.htm
Note that OUtlook VBA code is not meant to be distributed to other people. If your goal is an enterprise-wide solution, you'll want to build an Outlook add-in. But the VBA environment is a good way to do some initial prototyping.
