There seems to be support for cancellations in iCal's RFC. Have you tried
simply deleting an appointment that you sent as an iCal?

Hi Everyone, I am trying to figure out a way to delete events from my
Outlook
calendar using iCal. I am sure there is a way to do that as long as you
can
add events to outlook then there must be a way to delete events from
outlook
using iCal. If anyone knows how to do that, then please do let me know or
if
there is an alternative solution then I'll be more interested to know!!!
