I receive a lot of calendar invitations to my GMail account, where I can accept them and with a few manual steps add them to my calendar. However, if the sender later on cancels the event it disappears from my calendar automatically.
Is there a way to prevent this? Or at least make it a manual process?
Most of the time I would like the events to remain in the calendar, even though they should be marked as cancelled, because I use the calendar for invoicing and even cancelled events are, most of the time, charged.
