How is "Calendar Sharing" enabled in Exchange Server?

"Calendar Sharing" in Exchange Server is enabled by adjusting sharing permissions within a user’s Outlook settings or the Exchange Control Panel (ECP). This approach allows users to specify which individuals or groups can view their calendars and what level of access they have, such as whether others can just view the calendar or also modify or add events.

Setting sharing permissions directly within these applications provides a straightforward method for managing visibility and access, ensuring that users can tailor their calendar sharing to their preferences and requirements. This level of control is essential for maintaining privacy and security over calendar information, while also facilitating collaboration when granted.

The other options presented do not provide a direct method for enabling calendar sharing in Exchange Server. Publishing a calendar on a public URL may make it accessible, but it does not offer the streamlined permission management necessary for effective sharing among specific users. Sending calendar invites to contacts relates to sharing specific events rather than establishing broader calendar sharing settings. Utilizing third-party applications could offer additional functionalities but does not constitute the built-in sharing mechanism provided by Exchange Server itself.
