Can Cronofy’s access be restricted to free/busy information? 
An essential part of the calendar integration feature is the actual creation of events in your company calendar. In order to do so, we need the access right to write entries in your company's calendar (write scope). Unfortunately, restricting access to free/busy information does not grant us this write scope and prevents us from creating events.
Can Cronofy’s access be otherwise restricted or monitored? 
Yes. For more information about using the calendar synchronization with Office365 and Exchange, click here. For more information about using it with G-Suite, click here.
