As announced at Macworld Expo in January, the Office 2004 for Mac 11.2.3 Update brings Sync Services integration, Spotlight support and enhanced Smart Card technology. New support for Sync Services enables customers to sync calendar events, contacts and tasks with handheld devices and other applications that support Sync Services, including Apple's own Address Book. Spotlight support allows users to search Entourage 2004 emails and information, while the enhanced Smart Card technology leverages Apple’s Keychain to allow users to digitally sign and encrypt mail.
