Hi, we have just experienced a loss of an important and major work calendar which seems to be deleted. I'm shocked to learn that if someone with editing permission to a calendar (add a / and delete events) by mistake or purpose delete the calender. It is impossible for the main user to restore ore back up their own calendar information. This is in my concern a major security concern.
Do you have any way around this? If not it should be dealt with asap as this is crucial breach of security!
I’d open a ticket with Google Support (see https://support.google.com/a/answer/1047213?hl=en) and see if they can restore it for you.
Hope that helps,
Ian
