2.1.3.1.1.8 Property: X-MICROSOFT-CALSCALE

RFC Reference: N/A

Number of Instances Allowed: 0,1

Format: Text ([RFC2445] section 4.3.11)

Brief Description: Identifies the calendar type of a non-Gregorian recurring appointment.

Importing to Calendar objects

If this property is specified, then it SHOULD<13> be imported for every VEVENT that declares an X-MICROSOFT-RRULE.

This property SHOULD<14> set the CalendarType field of the RecurrencePattern field of the AppointmentRecurrencePattern structure ([MS-OXOCAL] section 2.2.1.44.5) in the PidLidAppointmentRecur property ([MS-OXOCAL] section 2.2.1.44). See also sections 2.1.3.2.2.1, 2.1.3.2.2.2, 2.1.3.2.2.3, 2.1.3.2.2.4, 2.1.3.2.2.5, and 2.1.3.2.2.6.

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.

Additionally, for certain values of the PatternType field of the RecurrencePattern field of the AppointmentRecurrencePattern structure, this property SHOULD<17> be exported as specified in the following table.
