Here's the problem - I have a backup of Outlook 2003 data files (I
assume all of the pst files too) from my old XP computer and I have
installed it in a Vista Home Premium extra slot that also has Outlook
2003. The computer reads it as F: drive and shows many numbers for
files. But every time I try to open one, I'm denied access.

These are all my data files from my old computer, which I need badly.
Can you help?
