Mac OS X 10.6 Snow Leopard comes with a great e-mail application (Mail), calendar application (iCal), and contacts manager (Address Book). But many people in the business world use Microsoft's Exchange products to handle all three functions, with Exchange Server on the back end managing everything and Entourage on the Mac (called Outlook in Windows) providing users with access to their e-mail, calendars, and contacts from the Exchange Server.
Microsoft has long made its Entourage application available for the Mac, so users have been able to work with Exchange for more than a decade. But Mac OS X 10.6 Snow Leopard now integrates the Microsoft ActiveSync technology, making it even easier to work in an Exchange Server-based business, especially if your business uses the newest version of that server, Exchange Server 2007.
