It is working when email is send in the outlook it is automatically cancelling the event when deleting event ics file is received in the email. It is striking the event in outlook calendar.

But when i am checking with gmail it is not removing event when delete event is received. After delete event is received in the email google calendar shows same event over there.

I only want to use PUBLISH method while creating event. Don't want use REQUEST method while creating event using ics file as it will create unnecessary RVSP option.

I have tried to keep sequence same that also didn't work. Even it tried adding X-WR-RELCALID this parameter even this was also not working.

尝试使用 METHOD:PUBLISH 但状态为：CANCELLED
