1.6 Applicability Statement
The Public Folder–Based Free/Busy Protocol is appropriate for use by higher layers of a server or client implementation that schedule meetings to avoid scheduling conflicts.
The following related functionality is best accomplished by using other protocols.
Displaying complete calendar details. This is best accomplished by receiving permissions and directly browsing the calendar of the meeting attendee or resource. For information about how a client opens the Calendar folder of another user, see [MS-OXODLGT] section 3.2.4.1.
Displaying free/busy data outside the publishing range. This is best accomplished by using the Availability service, as described in [MS-OXWAVLS].
It is recommended that this protocol be used only if the Availability service is not supported by the server.
