Two reasons (so far) why I would not uninstall Office 14 and return to Office 12...
1. Outlook can connect to more than one exchange server!
Just close, go to mail in control panel, and just add a new exchange account! It no longer stops you! :)
2. Translation!
All I did was mouse over, and office translates it to the language I choose previously.
Have not tested entire paragraph to see how accurate is, but I'm sure this would come in handy when working with off shore offices
