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

Question

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

Answer 1

I might need to set X-WR-RELCALID tag, according to this http://www.oesf.org/forum/index.php?act=Print&client=printer&f=63&t=2650

It states: "Before syncing for the first time, you MUST add a X-WR-RELCALID tag to the mycalendar.ics file, or else iCal will change the UID number of all entries, causing duplicates."

However I can't find any documentation on RELCALID tag in protocol http://tools.ietf.org/html/rfc2446

When I set X-WR-RELCALID, Outlook still creates duplicate events instead of removing those events.

Is there any documentation on X-WR-RELCALID? I can't find it.
