I run the following to create an .ics file which creates an entry / appointment within Outlook Calendar but the question is how to delete an entry via .ics ?
The aim is so the user gets the .ics file attached to the email, which adds the entry to the calendar when opened & saved. Now, if the user changes his mind, I like the same method to be delivered but the entry to be removed instead.
To add an appointment:
BEGIN:VCALENDAR VERSION:2.0 BEGIN:VEVENT .... ...... ......... END:VEVENT END:VCALENDAR
I have tried to add METHOD:CANCEL and STATUS:CANCELLED but is not working.
BEGIN:VCALENDAR VERSION:2.0 METHOD:CANCEL BEGIN:VEVENT .......... STATUS:CANCELLED END:VEVENT END:VCALENDAR
