I set up two accounts: A & B. A has only 1 calendar configured to be shared among internal members with manager rights. B has it's own calendar as well as a shared calendar linked to A's.
Two problems were found. First, appointments were set up by A but could not be seen by the linked calendar in B. Second, B entered appointments in the shared calendar (owned by A), but all were recorded in B's own calendar.
Did I do something incorrectly? All hints are welcome.
