Prevent publishing calendars to Office Online. - Outlook (Cat II impact)

Discussion

By default, Outlook 2007 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. If your organization has policies that govern access to external resources such as Office Online, allowing users to publish their calendars might enable them to violate those policies.
