The iCalendar property parameter "SCHEDULE-FORCE-SEND", defined in Section 7.2, can be used by a calendar user to force the server to send a scheduling message to an "Attendee" or the "Organizer" in a situation where the server would not normally send a scheduling message. For instance, an "Organizer" could use this property parameter to request an "Attendee" that previously declined an invitation to reconsider his participation status without being forced to modify the event.

Need to test your iCalendar feeds?

The iCalendar Validator provides developers and testers a method to validate their iCalendar feeds, which can take data from either a URL, file or text snippet and compare it against the RFC 5545 specification.  We believe we have one of the best iCalendar validation tools available on the internet. More information about the validator can be found here.
