220.127.116.11 String Handling
A server holds values of properties for objects. Some of these values are strings. The Exchange Server NSPI Protocol allows string values to be represented as 8-bit character strings or Unicode strings. All string valued properties held by a server are categorized as either natively of property type PtypString or natively of property type PtypString8. Those properties natively of property type PtypString8 are further categorized as either case-sensitive or case-insensitive.
