calendar server error
When I opened my Calendar on my MBP it has a triangle with an exclamation point next to the account name. Clicking on the icon gives the message: "The server responded with an error. There is insufficient storage space for “....iCloud”
What server?
My iCloud storage has 100.9 GB of 200 GB used.
Running Mojave 10.14.6
How do I fix the problem?
MacBook Pro (2017 – 2020)
