Digital forensics professionals routinely need to analyze PST email headers and MIME data for forensic investigation, since raw email header data contains routing information, IP addresses, timestamps, and server relay paths that aren't visible in standard email preview modes but are critical for establishing email authenticity and chain of custody. Opening a PST in standard Outlook only exposes the rendered email view — header details like Return-Path, Message-ID, MIME Version, and Content-Type are hidden behind the application's display layer and require switching to a dedicated header view that most Outlook configurations don't make immediately accessible. Exporting emails to EML first and then opening them in a text editor to inspect raw headers is a common workaround, but this adds an extra step that introduces the risk of file metadata being altered during the export process. SysInfo PST Viewer provides forensic-grade visibility directly within the tool, displaying raw email headers, MIME content, HTML source, and hex data in dedicated view panels without modifying the source file at any point. Message routing paths, sender IP addresses, and SMTP relay chains are all readable from within the same interface used to browse the mailbox folder structure. Audit-ready log reports document all activities performed during the session for compliance and evidentiary reference. Compatible with all Windows versions, including Windows 11.
