Hello: I was in my Entourage mailbox this morning and it worked fine. Went on to do other things and cam back to the computer to check email and Entourage opened up like it was brand new and asked me if I wanted to make this my default email?? No addresses, no emails and no folders are in this Entourage. Where would my original Entourage have gone. I haven't deleted anything. I am using Mac OSX 10.4 (Mac/Windows). Thanks for your help.
