My OS = XP Media Center Edition. Office Professional 2003

I backed up my OL with a personal folders file before reinstalling windows.
After reinstaling windows I copied the saved personal folders file to my
documents on the hard drive. Then in OL: NEW OPEN OUTLOOK DATA FILE, I
attempted to open the personal folders file and I was prompted for a
password. I never set a password to my personal folders file. Does anyone
know how I can "import" my OL personal folders file? Programs on the web
claim to be able to "find" my password but I'm distrusting of scams, malware,
etc
