Delete calendar event using iCalendar file import (Outlook 2003 problem)

icalendaroutlook

Is there a way for me to delete items from calendar by using iCalendar import?

I know that there is a METHOD:CANCEL, however when I tried it, it didn't do anything to the calendar event.

Here is what is in my iCalendar file. When I try to import it to Outlook, it just adds these events.

Best Solution

I forgot to add STATUS:CANCELLED

Now this should cancel items according to http://en.wikipedia.org/wiki/ICalendar#Events_.28VEVENT.29

This works in Google Calendar but not in Outlook 2003. Outlook still creates duplicate entries.

Here are modified "cancel" events with 'STATUS:CANCELLED'. (British spelling with two L's)
