ZDNet's All About Microsoft blog claims that Apple's iPhone will be compatible with Microsoft Exchange Server.
Heres what Im hearing: Apple will announce this week possibly as soon as June 27 that it has licensed the Exchange ActiveSync licensing protocol. Via the licensing arrangement, Apple iPhone users will be able to connect to Exchange Server and make use of its wireless messaging and synchronization capabilities.
The presumed lack of Microsoft Exchange support was a criticism amongst analysts regarding iPhone's fit in the business world.
