Outlook 2003 makes it possible to view multiple calendars side-by-side in the Outlook window including local, public folder and other users' calendars. The calendars scroll together and are colour-coded, making them useful for comparing schedules. Users can drag appointments between calendars or onto their own calendar or use the New Meeting With feature to quickly set up a meeting with the owners of some or all of the open calendars.
Note: This feature is not available while working Offline.
