Ever saved your email to a PST file and password protected the file and then 6 months later went to open the PST file and you can't remember the password? Here is a tool for you! Nirsoft, one of my favorite sitr for password utilities has released PstPassword.
This utility can recover the PST passwords of Outlook 97, Outlook 2000, Outlook XP, and Outlook 2003. You don't have to install MS-Outlook in order to use this utility. You only need the original PST file that you locked with a password.
