Microsoft Outlook 2003 is part of the Microsoft Office 2003 Suite, first released on 17th November 2003.
The Preview Pane found in earlier versions of Outlook has been renamed The Reading Pane and redesigned and optimised for reading e-mail messages. Like a piece of paper, the Reading Pane is laid out vertically and, when used with the new multi-line layout, displays nearly twice as much information on the screen as the Preview Pane did. Other enhancements include the ability to respond to meeting requests and to use voting buttons without having to open the messages first.
The Calendar view has been streamlined, and you can now view multiple calendars at once. In this view, the TaskPad is hidden, and the Date Navigator now is displayed in the Navigation Pane. A new indicator makes it easy to quickly see the current day and time.
