For appointments with an X-MICROSOFT-CALSCALE value of "Hijri", the value for PatternType (as specified in [MS-OXOCAL] section 2.2.1.44.1) and CalendarType depend upon the imported value of PatternType. PatternType SHOULD be determined as specified in section 2.1.3.2.2. The resulting value SHOULD then be overwritten as specified in the following table.

Exporting from Calendar objects

Since this property is a child of the VCALENDAR, a VCALENDAR MUST NOT contain any two VEVENTs that would result in different values of X-MICROSOFT-CALSCALE.

If the CalendarType field of the RecurrencePattern field of the AppointmentRecurrencePattern structure is nonzero, then this property SHOULD<16> be exported as specified in the following table.
