Our legal team recently requested access to several Outlook PST archives as part of an internal investigation. The challenge was that we didn't want to restore everything into Outlook or alter the original mailbox data during the review process. We simply needed a PST viewer that could safely inspect archived emails while preserving all the original information.
After testing a few options, I tried MacSonik PST Viewer Pro, and it seemed to be designed with these kinds of scenarios in mind. Since it works independently of Microsoft Outlook, we could open PST files directly on both Mac and Windows systems without setting up additional mail profiles.
What impressed me most was the level of detail available during preview. Besides viewing email content and attachments, the software displays complete internet headers, sender and recipient information, timestamps, MIME structure, and raw HTML. For compliance reviews and forensic analysis, having access to this metadata without modifying the source file is extremely valuable.
The advanced search feature also reduced the amount of manual work. Instead of browsing thousands of messages, we could filter emails by sender, recipient, subject, attachment status, or a specific date range. That made locating relevant conversations much faster, especially when working with archived mailboxes containing years of correspondence.
Another advantage was its support for multiple mailbox components. It wasn't limited to emails—it also allowed us to inspect contacts, calendars, tasks, notes, drafts, deleted items, and complete folder structures. Everything remained organized exactly as it appeared in the original PST, making it easier to understand the context of conversations.
From a compliance perspective, local processing was another plus. None of the mailbox data was uploaded to external servers, which helped satisfy our organization's security policies. The software also generated detailed activity and export logs, providing an audit trail that documented every operation performed during the review.
Although our primary goal wasn't migration, I noticed that selected mailbox data could later be exported into PST, PDF, EML, MSG, MBOX, CSV, or even Microsoft 365 if required.
