After re-installing Small Business Server 2003 with a different Domain Name, I then needed to change the PC user account on their individual PCs. After selecting the new Domain and restarting the PC, windows XP treated the change as if I had created a new user. Windows created new settings for the user and all of the Outlook files were gone. Did Windows archive/back them up somewhere? Why did Windows create new settings for the same user?Thanks for your help!1 person got this answerI do too
