PROP_TYPE (ulPropTag)
The PROP_TYPE macro can be used to determine the type of a property. For example, calling PROP_TYPE(PR_ENTRYID) results in the value PT_BINARY being returned.
Every property tag contains the property type in the low-order word (bits 0 through 15) and the property identifier in the high-order word (bits 16 through 31). The PROP_TYPE macro extracts the property type and places it in bits 0 through 15 of the integer to be returned. The remaining bits of the return value are set to zeros.
