2.11.1 Property Data Types

For all variants, the structure of a property value is the same and is specified by the property data type, whether or not the property data type is actually encoded in the buffer. The following table lists both the property data type identifiers and the format of the property values. Web Distributed Authoring and Versioning Protocol (WebDAV) property data type identifiers are specified in section 2.11.1.6.

There is one variation in the width of count fields. In the context of ROP buffers, such as the RopGetPropertiesSpecificROP ([MS-OXCROPS] section 2.2.8.3), byte counts for PtypBinary property values and value counts for all PtypMultiple property values are 16 bits wide. But in the context of extended rules, as specified in [MS-OXORULE] section 2.2.4, byte counts and property value counts are 32 bits wide, and in the [MS-OXCMAPIHTTP] protocol, the byte counts for PtypBinary property values are also 32 bits wide. Such count fields have a width designation of COUNT, as specified in section 2.11.1.1, rather than an explicit width, as throughout section 2.11.

In the context of a table operation, properties are referred to as columns. The format of property identifiers, types, and values in table operations such as the RopQueryRows ROP ([MS-OXCROPS] section 2.2.5.4) is the same as in property operations such as the RopGetPropertiesSpecific ROP. Property data types are presented in the following table. The property data type values specified are 16-bit integers. The Name Service Provider Interface (NSPI) Protocol, as specified in [MS-NSPI], uses the same numeric values but expresses them as 32-bit integers, with the high-order 16 bits of the 32-bit representation set to 0x0000.
