I installed Leopard and all looked great...but then...Entourage was in a new format, and all of the emails that I had put into their own business file were missing!! I have looked through the system using both spotlight and digging in old folders. It is gone. Do I chalk this up as lesson learned for backing up emails, or has this happened to others (and is there a solution). Please help. The irony...I upgraded to use Time Machine so I wouldn't lose my important email.
