I have problems with sharing rights on the calendar.
Here is the scenario:
John Doe has a shared calendar with his assistant.
It gives him only the right to add an event because he did not want his
assistant delete or edit events that he himself created.
With this setting, the assistant can add an event, but once created it can
not modify or delete some error.
It would be desirable that the assistant can modify or delete events that he
added to the calendar of John Doe.
Is it possible that the assistant has full control of events added to the
calendar of John Doe ?
