2.2.1.27 PidLidGlobalObjectId Property

Type: PtypBinary ([MS-OXCDATA] section 2.11.1)

The PidLidGlobalObjectId property ([MS-OXPROPS] section 2.142) specifies the unique identifier of the Calendar object. After it is set for a Calendar object, the value of this property MUST NOT change. The fields in this binary large object (BLOB) are specified in the following table. All fields have little-endian byte order.

Byte Array ID (16 bytes):  An array of 16 bytes identifying this BLOB as a Global Object ID. The byte array MUST be as follows: 0x04, 0x00, 0x00, 0x00, 0x82, 0x00, 0xE0, 0x00, 0x74, 0xC5, 0xB7, 0x10, 0x1A, 0x82, 0xE0, 0x08.

YH (1 byte):  The high-ordered byte of the 2-byte year from the PidLidExceptionReplaceTime property (section 2.2.10.2.5) if the object represents an exception; otherwise, zero.

YL (1 byte):  The low-ordered byte of the 2-byte year from the PidLidExceptionReplaceTime property if the object represents an exception; otherwise, zero.

M (1 byte):  The month from the PidLidExceptionReplaceTime property if the object represents an exception; otherwise, zero. If it represents an exception, the value MUST be one of those listed in the following table.

D (1 byte):  The day of the month from the PidLidExceptionReplaceTime property if the object represents an exception; otherwise, zero.

Creation Time (8 bytes):  A FILETIME structure ([MS-DTYP]) that specifies the date and time when this Global Object ID was generated.

X (8 bytes):  Reserved, MUST be all zeros.

Size (4 bytes):  This field specifies the size of the Data field.

Data (variable):  An array of bytes that ensures the uniqueness of the Global Object ID among all Calendar objects in all mailboxes.
