It turns out that the Outlook Public folder values I need are not available via the object model(OLE). They are available only via CDO. I think CDO can be used in limited capacity on the systems I'm using, but CDO looks like more work than I'm interested in doing.
I found a tool that will get me the data I need. Its called pfinfo.exe
Its download-able from ftp://ftp.microsoft.com/PSS/Tools/Exchange%20Support%20Tools/PFInfo/55/
thanks for the guidance.
