Publishing calendars to Office Online must be prevented.

V-71129 DTOO216 SV-85753r1_rule Medium
Description
Outlook users can share their calendars with selected others by publishing them to the Microsoft Office Outlook Calendar Sharing Service. Users can control who can view their calendar and at what level of detail. When an organization has policies that govern access to external resources such as Office Online, allowing users to publish their calendars will enable them to violate those policies.
