We bumped into this on the spambayes project.  IMO doesn't support CDO
(Collaboration Data Objects) out of the box, but an IMO user can easily
install CDO from their Office CD.  Mark Hammond found faster & better (but
seemingly more obscure) ways to replace CDO calls via extended MAPI calls
instead, and then spambayes worked for everyone.  There are still some
challenges in actually working with Exchange server installations, largely
because no spambayes developer has access to one.  It's not a lack of docs,
it's a lack of comprehensible docs <0.9 wink>.
