No Longer Getting Calendar Event Email Notifications

No Longer Getting Calendar Event Email Notifications

My calendar events have a default for email notification 1 hour before. But now I am not getting them, maybe just the last day or two. I have checked several and they show as expected. I created about 5 test events with 5 minute email notification, but none ever came, not in spam, trash, archive folders... and a search of all mails folders shows nothing.
