Password Encryption in PST File

The password encryption in the PST file is very weak, and for each password-protected PST file, there are many passwords that can open it.
PstPassword provides 3 different passwords for each password-protected PST file. It's possible that one of them will be the original password that you typed, and it's also possible that none of these passwords will be identical to the original one. However, all 3 passwords provided by PstPassword will open the PST file without problems.

Using PstPassword

PstPassword doesn't require any installation process or additional dll files. In order to start using it, just run the executable file, PstPassword.exe
After you run PstPassword, the main window displays the list of all PST files of the current logged on user (Under Documents and Settings\User Name\Local Settings\Application Data\Microsoft\Outlook). For each password-protected PST file, PstPassword provide 3 alternative passwords that will open the PST file. If the PST is not protected by a password, the 3 password columns remain empty, and the CRC value column is 0x00000000.
If you want to recover a password of PST file that doesn't appear in the default list, you can press F7 and select the desired PST file, or simply drag the PST file from Explorer window into the main window of PstPassword.
If from some reason PstPassword fails to read a PST file, an error message is displayed under the error column, and the item is painted with pink color.
