[Zope] MS Exchange

My organization uses Microsoft Exchange 5.5 (ptui!) for e-mail and collaboration. We have a Public Folder called "Company Contacts" which is our company-wide contact list. I want to access that from Zope. I'm running Zope off of a Red Hat Linux 6.1 box. There doesn't seem to be a way to get to it from LDAP (grumble), and IMAPv4 is only giving me limited information (Contact Name and Notes). I don't think there's a way to do it with COM or MAPI (as my Zope server is Linux), but I'm not sure. My last ditch will be to write an ASP page running on the Exchange server to present that info to Zope for processing. If anyone could provide me with more insight or better solution, I'd love to hear it. TIA.
