Now that the public beta of Exchange Server 2010 is available, there are some technical documentation that is also being released:
- Microsoft Exchange Server 2010 Beta Protocol Documentation – The Microsoft Exchange Server 2010 Protocol technical documentation set provides detailed technical specifications for Microsoft protocols and extensions to industry-standards or other published protocols that are implemented and used in Microsoft Exchange Server 2010. This allows the user to interoperate or communicate natively with Microsoft Office client and other server products.
The documentation is designed to describe each protocol in detail as it is used by the Microsoft Exchange Server. Each protocol specification documents the technical requirements, limitations, dependencies, and Microsoft-specific protocol behavior.
The documentation set 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. - Microsoft Exchange Server 2007 Standards Documentation – The Exchange Server Standards Documents provide information about Exchange 2007 support for industry messaging standards and Requests for Comments (RFCs) related to iCalendar, IMAP4, and POP3.
