PST Viewer

PST Viewer provides browser-based access to Outlook PST contents without local installation. It parses PST structures, builds an index of messages, attachments, and metadata, and presents results in a searchable view. The tool emphasizes data governance, auditability, and quick triage for investigations. The underlying approach is to stream or chunk-process PST data, extract headers, subjects, dates, senders, recipients, and attachment names, then render previews and export options. Users benefit from rapid discovery, scenario testing, and reproducible workflows across teams. Core differentiators include scalable parsing, privacy-conscious processing modes, and robust export formats for eDiscovery or archival projects. Use cases include incident response, compliance reviews, mailbox migrations, and forensic analysis. The tool focuses on accuracy, performance, and safety, avoiding full data replication and enabling selective extraction.
It supports batch processing, multiple PSTs per session, and configurable filters to narrow results by date, sender, recipient, or attachment type. The architecture favors deterministic results, clear provenance, and exportable metadata alongside messages.
In practice, analysts upload PSTs, run targeted searches, preview messages, and extract attachments or save results as CSV, EML, or JSON records. This delivers a lightweight, accessible option for teams that need quick access to historical email content without desktop software. The value lies in faster investigation cycles, lower hardware barriers, and easier collaboration across distributed teams.
