Good news for those upgrading to Outlook 2011 (part of Office 2011)… email messages are now stored as individual files! This means the email database is much smaller, less prone to corruption, and is finally Time Machine friendly.

Bad news for companies still running Exchange 2003, Outlook 2011 only works with servers running Exchange 2007 or later. If a working copy of Entourage installed, it will continue to work after installing Office 2010.
