A Different Perspective On Snow Leopard's Exchange Support
imamac writes "Apple Insider has an interesting perspective on the MS Exchange support built into Mac OS X 10.6 and how it essentially frees Apple from all things Microsoft: 'Windows Enthusiasts like to spin Apple's support for Exchange on the iPhone and in Snow Leopard as endorsement of Microsoft in the server space. From another angle, Apple is reducing its dependence upon Microsoft's client software, weakening Microsoft's ability to hold back and dumb down its Mac offerings at Apple's expense. More importantly, Apple is providing its users with additional options that benefit both Mac users and the open source community.'"
The article says:
"Apple built its support for Exchange using WebDAV..."
Untrue. The Exchange support for Snow Leopard was built using Exchange Web Services, just like the next version of Microsoft's client, Entourage.
There is no single "Exchange Protocol." What you might be talking about is MAPI, the protocol Outlook uses to talk to Exchange (and the oldest protocol Exchange supports, I believe). MAPI is full documented on MSDN, and there are a number of open source implementations of MAPI (see http://en.wikipedia.org/wiki/MAPI).
However, the Exchange support in Snow Leopard doesn't use MAPI, it uses Exchange Web Services, which is also open and documented on MSDN.
