Member name	Value	Description
Unspecified	0	Any: this property type value matches any type; a server MUST return the actual type in its response. Servers MUST NOT return this type in response to a client request other than NspiGetIDsFromNames or the RopGetPropertyIdsFromNames ROP request ([MS-OXCROPS] section 2.2.8.1). Specification name: PtypUnspecified; Alternate names: PT_UNSPECIFIED;
Null	1	None: This property is a placeholder. Specification name: PtypNull; Alternate names: PT_NULL;
Integer16	2	2 bytes; a 16-bit integer Specification name: PtypInteger16; Alternate names: PT_SHORT, PT_I2, i2, ui2;
Integer32	3	4 bytes; a 32-bit integer Specification name: PtypInteger32; Alternate names: PT_LONG, PT_I4, int, ui4;
Floating32	4	4 bytes; a 32-bit floating point number Specification name: PtypFloating32; Alternate names: PT_FLOAT, PT_R4, float, r4;
Floating64	5	8 bytes; a 64-bit floating point number Specification name: PtypFloating64; Alternate names: PT_DOUBLE, PT_R8, r8;
Currency	6	8 bytes; a 64-bit signed, scaled integer representation of a decimal currency value, with four places to the right of the decimal point Specification name: PtypCurrency; Alternate names: PT_CURRENCY, fixed.14.4;
FloatingTime	7	8 bytes; a 64-bit floating point number in which the whole number part represents the number of days since December 30, 1899, and the fractional part represents the fraction of a day since midnight Specification name: PtypFloatingTime; Alternate names: PT_APPTIME; The date information is represented by whole-number increments, starting with December 30, 1899 midnight as time zero. The time information is represented by the fraction of a day since the preceding midnight. For example, 6:00 A.M. on January 4, 1900 would be represented by the value 5.25 (5 and 1/4 of a day past December 30, 1899).
