Exchange Server Protocols

The Microsoft Exchange Server Protocols documentation provides detailed technical specifications for Microsoft proprietary protocols (including extensions to industry-standard or other published protocols) in the Microsoft Exchange Server system.

The Microsoft Exchange Server Protocols documentation provides specifications for protocols that are implemented in the Microsoft Exchange Server system software and that are used to communicate with other products.

The documentation is designed to describe each protocol in detail as it is used by the Microsoft Exchange Server system. Each protocol specification documents the technical requirements, limitations, dependencies, and Microsoft-specific protocol behavior.

The documentation also includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information, such as common data types and error codes.
