Help updating an event in Outlook 2007 with an iCalendar file
How do I update calendar events that were imported by iCalendar file?
I need to re-import events but I want to make sure that the existing events are updated. Currently if I do an import, it adds additional event instead of updating existing event on my Outlook calendar.
BEGIN:VCALENDAR
VERSION:1.0
BEGIN:VEVENT
UID:123@mydomain.com
METHOD:REFRESH
CATEGORIES:MEETING
STATUS:TENTATIVE
DTSTART:20081125T233000Z
DTEND:20081125T233000Z
SUMMARY: Updated Event 2. Imported From iCalendar File.
DESCRIPTION:This is a test
CLASS:PRIVATE
END:VEVENT
END:VCALENDAR
I'm trying to use METHOD: REFRESH I also tried METHOD: REQUEST but it still adds additional event instead of updating existing event on my Outlook calendar.
