Sync Entourage-iCal synchronizes Entourage 2004 [ONLY!] and iCal in Tiger (OS 10.4: see altenate link for Panther version.). It allows you to maintain Entourage as your centralized Personal Information Manager while at the same time taking advantage of the direct access provided to iSync, iChat, iPod, .Mac online, and more by OS X's iCal. Almost all Entourage fields sync to iCal and back, with any unmapped fields recorded in event Notes. You can also sync Entourage reminders to iCal alarms, including Email alarms. You can keep both applications in constant synchronization by running the script at any time, or automatically every night if you wish.
What's new in Sync Entourage-iCal
