Automate Import of VCalendar in Outlook

Hi ,
I'm trying to automate import of VCalendar/ICalendar attachment using Outlook 2000 / 98, but only found a way to forward Appointment objects (CDO / Outlook Extensions) as ICalendar. When u receive attachment of an ICal/VCal file u can double click it and outlook will add it to your calendar.
Also I found a library at www.imc.org but it's not compatible with the current version of ICalendar (2.00 or above).

Thanks in advance,
