I recommend using ToolsGround PST Password Recovery Software for a quick and safe way to recover passwords from PST files. Because of the PST file’s graphical user interface (GUI), even non-techies can recover the password from it. The program supports both ANSI and UNICODE PST files for password recovery. This program allows you to recover passwords from any PST file without the need to install Microsoft Outlook. To give the program a try for free, install the most recent trial version.
