Exploring with Microsoft Exchange Server Protocols docs
Recently I got requests from the developer community regarding my earlier article – so I take this opportunity to point how you can explore more about Microsoft Exchange Server Protocols. As you know through the Open Specifications program, Microsoft is helping developers open new opportunities by making technical documents related to interoperability for certain popular Microsoft products available to view and download from MSDN at no charge. Although the technical documents are freely available, many of them include patented inventions. Some of these patents are available at no charge under the Open Specifications Promise or the Microsoft Community Promise. The remaining patents are available through various licensing programs. For more information, please visit the Open Specifications Dev Center website.
When your look for Exchange Server specific then you can explore Exchange Server Protocols documentation at:
Exchange Server Protocols Overview Document : It provides information about the protocols and other technologies that are included in the Exchange Server Protocols documentation set and the relationships among those technologies.
Exchange Server Protocols Technical Documents : It provides detailed technical specifications for Microsoft proprietary protocols (including extensions to industry-standard or other published protocols) and other technologies that are used by Exchange Server to communicate with other Microsoft products.
If you’re interested in Microsoft PST file format (.pst) then you can have a look at the https://msdn.microsoft.com/en-us/library/office/gg615595(v=office.14).aspx and the Protocol documentation for it’s available @ https://msdn.microsoft.com/en-us/library/ff385210(v=office.12).aspx
If you got any questions on these documents then please reach out to the related MSDN Forums: http://go.microsoft.com/fwlink/?LinkId=330023. Also you can have a look at the blogs authored by the engineers who support Open Specification documents.
Hope this helps.
