I cannot get the program to open now, although it did at first. I keep
getting this error message: Cannot start Microsoft Outlook (2003). Unable
to open the Outlook window. The set folders could not be opened.

I printed out the solution from Mircosoft - Article ID: 822503 - but I
don't seem to be able to understand what is needed here. Do I have to
uninstall Outlook 2003 and re-install? How do I prevent the same thing
happening again.
