Had this numerous times: someone planned a meet in my calendar without getting a notice somewhere (preferably by mail) that this happened.
Result: getting of meeting notice 10 min before, without me even knowing it was planned.
Must be some setting to change this?

If you haven't done this, you can add/edit notifications in Calendar settings. The default is a popup notification 10 min. before the event so I suspect you haven't edited this.
In here you can Add/edit a notification, choose to get an email or sms when someone invites you to an event, receive a daily agenda etc.
