Big Sur - Disable the iCloud Calendar Services

Information

The macOS built-in Calendar.app connection to Apple's iCloud service _MUST_ be disabled.

Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, automated calendar synchronization _MUST_ be controlled by an organization approved service.

Solution

This is implemented by a Configuration Profile.

mobileconfig profile info:

com.apple.applicationaccess:
allowCloudCalendar:
False
