The release of Microsoft's specifications for the Outlook Personal Folders (.PST) file format in 2010 was a watershed moment for digital forensics. It opened doors for developers, enabling them to read and write .PST files more effectively. Given that Microsoft Outlook is ubiquitous across both home and corporate environments, understanding and analyzing .PST files has become crucial for forensic investigators.

The Kernel Outlook .PST Viewer stands out as an excellent free tool for viewing .PST files.
No Need for MS Outlook Installation: Unlike many other tools, the Kernel viewer doesn't require MS Outlook to be installed on your system.
Support for ANSI and Unicode Formats: It can handle both ANSI and Unicode formats of .PST files, ensuring compatibility across different versions of MS Outlook.
