My work is in the process of upgrading everyone to Office 2003. I went ahead and grabbed it because I use Microsoft OneNote, and it integrates with 2003, but not 2002 that we had been using previously. It rocks. I love the improvements they’ve made. There’s a list of things that I wanted them to add, that I’d looked for or found add-ons for, and all of those things are present/fixed now. 🙂 Yay!
Examples of stuff they added/fixed:
Outlook can minimize to a tray icon
Calendar has a month navigator in the left pane
Better automatic formatting and rules
Calendar has a clear “TODAY” indicator in month view
Can change the color of calendar background
