I have created an ICS file using your export. But I haven't been able to figure out what I need to change in order to update the event. I tried to change the things like dtstamp, last-modified, status, important, created, priority (all ofcourse higher than the current setting but with time settings I changed it to a few seconds later so that it is in a time that already passed and somewhere in the future). Ofcourse I didn't change the UID. So what do I need to do to update the event?
Is it posible to create new and edit appointment in the same ICS file?
Also is it posible to change multiple calendars on the same account in 1 ICS file?
And final question: when I import an ICS as a new appointment (maybe also edit an appointment, but since I can't get this to work I don't know yet) it shows a clock in the appointment (see attached photo). I asume it has something to do with it being an unconfirmed appointment or something but is it posible to create / update the events so that it doesn't show the clock? Cause I know I will get the question from the employees here why some appointments do have it and others not.
Thanks in advance.
