Outlook 2003 pst files

[Potatoman]

Hi all - i had to reformat my drive recently, and i backed up my outlook pst files (inbox contacts, etc) When i tried to open outlook again and open the pst files, it says i dont have sufficient permission to do so. How can i change this? I was using XP but now Vista. What i have now is dual boot with Vista and XP, and my pst files on an external hard drive. Works fine in XP, but in vista... computer says no! Insifficient privilages or something. Any ideas anyone? Thanks PM.

check the privileges on the xp sector and make sure they are not limited.
