Calendar Error message: "Your Calendar couldn't be refreshed". What does it mean? What should I do?
I opened my Calendar when I realised that it was not open and got the following message:
"Your calendar couldn't be refreshed.
Access to account 'Google' is not permitted.
The server responded: "403" to operation CalDAVRefreshDelegateListQueueableOperation".
BTW: I'm using a MacBook Air (13-inch, Early 2015) running macOS High Sierra v 10.13.6
