Cocoa. Built from the ground up using Cocoa providing users with improved integration with the Mac OS

New database. A high-speed file-based database with support for backing up files with Time Machine and Spotlight searching

“Microsoft Outlook and Exchange Server have been a cornerstone of communications and collaboration for our enterprise customers,” said Takeshi Numoto, corporate vice president of the Office product management group at Microsoft. “Today’s release of the Web Services Edition strengthens Exchange connectivity for Entourage customers and sets the stage for the move to the new application — Outlook for Mac. These updates continue Microsoft and the MacBU’s tradition of delivering the most complete solution to help customers manage their time, and better share their information and collaborate with others.”
