I originally had this problem with Outlook 2000, I tried all the microsoft knowledge base solutions, and they were of no help; none of them were. So in an atempt to solve my problem I upgraded both XP to Professional and Microsoft Office to 2003. After, wading through install problems with each and more pressing SP2 problems it seems even tho I uninstalled 2000 and installed 2003 the data remained and I still have the same problem in the title. All I am trying to do is save a contact; I dont think I can save anything in Outlook, and I cant get past this. I realize this is negative, but dont reply just to wash your hands because of the XP upgrade; in fact, dont reply to wash your hands period. I have allot experience with IT and support, and I know all the games. Oh one more time try to look in the Microsoft knowledge base if u want, but I am very sure the ans IS NOT THERE.
