opening archived pst file in outlook or outlook express

I have my old Outlook emails archived in a pst file. After a crash I had to reinstall XP and SP2. When I now try to import my old emails into reinstalled Outlook or Outlook Express from this pst file, a message pops up saying I do not have permission to do this. The MS website talks about having to use the right "identity". How do I change identities?

 

Thank you for your help Halo. I am sure it is the right track. But I started the computer in safe mode as your link suggested. I logged on either with my account name (which is listed as "computer administrator"), or as "administrator". The "administrtor " logon produced fewer icons in the final safe-mode windows screen. But in both cases my pst file only showed a "general" tab, not a "security" tab. I have Windows XP Home Edition and FAT 32 formatting on my hard drive. The pst file with my email archive had been on a CD, but I have now moved it to my hard drive. Without a security tab I cannot continue with the procedure in "How to take ownership of a file" (308421).

 

Thanks again for trying Halo. I had actually unchecked the "display simple file sharing while in Explorer..." when I was in safe mode before. Forgot to mention it. I have just tried unchecking "Read only" on the pst file (while in normal mode) but the security tab did not appear, even after a reboot. None of the boxes are now checked, neither "read only", "hidden", nor "archive".

 

Security tab is only for NTFS driver, NOT fat32.
