When a scheduling object resource is removed by an "Attendee", the server's behavior depends on the value of the "SCHEDULE-AGENT" iCalendar property parameter on the "ORGANIZER" iCalendar properties:
+----------------+--------------------------------------------------+ | SCHEDULE-AGENT | Action | +----------------+--------------------------------------------------+ | SERVER | The server will attempt to process the removal, | | (default) | taking into account any "Schedule-Reply" request | | | header as per Section 8.1. | | | | | CLIENT | The server does no special processing of the | | | resource. The client is assumed to be handling | | | any "Attendee" replies, etc. | | | | | NONE | The server does no special processing of the | | | resource. | +----------------+--------------------------------------------------+
