2.2.2.26 FirstDayOfWeek

The email2:FirstDayOfWeek element<11> is an optional child element of the Recurrence element (section 2.2.2.49) that specifies which day is considered the first day of the calendar week for the recurrence. It is defined as an element in the Email2 namespace.

A command request has a maximum of one email2:FirstDayOfWeek child element per Recurrence element. A command response has a maximum of one email2:FirstDayOfWeek child element per Recurrence element.

This element disambiguates recurrences when attendees live across localities that define a different starting day for the calendar week. If this element is not included in the client request, the server SHOULD identify the first day of the week for this recurrence according to the preconfigured options of the user creating the calendar item.

The value of this element is an unsignedByte data type, as specified in [MS-ASDTYPE] section 2.7.

The value of the email2:FirstDayOfWeek element MUST be one of the values listed in the following table. If the client uses the Sync command request ([MS-ASCMD] section 2.2.2.19.1) to transmit a value that is not included in this table, the server MUST return protocol status error 6 in the Sync command response ([MS-ASCMD] section 2.2.2.19.2). Sync command status values are specified in [MS-ASCMD] section 2.2.3.162.16.
