When PST files are collected for legal eDiscovery, the challenge is not simply opening the mailbox and reading emails. The archive may contain years of communications, attachments, contacts, calendars, notes, tasks, drafts, and other Outlook data. A careful inspection process is needed to identify relevant information while keeping the original mailbox data intact.

The first thing I would look for is a way to examine the PST without changing the source file. This is especially important when the mailbox may be used as part of a legal investigation or compliance review. Being able to inspect message headers, timestamps, sender and recipient information, MIME content, HTML data, and attachments can provide a more complete picture of the available evidence. Search and filtering are also useful when the archive contains a large number of messages.

For this type of review, SysInfo PST Viewer can open healthy as well as corrupted, orphaned, blank, oversized, and password-protected PST files without requiring Microsoft Outlook. It supports ANSI and Unicode PST files and can load single or multiple PST/OST files. The preview includes emails along with contacts, calendars, tasks, notes, journals, drafts, RSS feeds, and other mailbox components. Its read-only operation is also designed so that the original PST is not overwritten or modified during viewing.

Once the mailbox has been inspected, the next step is usually identifying the specific records that need to be retained or presented. Advanced search options can help locate messages using sender, recipient, subject, date range, or attachment status. Text-based filtering can further narrow results based on To, From, and Subject criteria. Duplicate removal may also help eliminate repeated messages before exporting relevant information.

For legal teams and investigators, a PST File Viewer can also be useful when selected email records need to be preserved in more accessible formats. The software supports exporting mailbox data to PST, EML, MSG, MBOX, PDF, and CSV. PDF export can create individual or merged documents, while attachments can be retained with emails, separated into another location, or handled according to the review requirements.

I’d like to know how others approach PST eDiscovery. Do you normally inspect headers and metadata before reviewing message content, or start with keyword and date-based filtering? What steps do you follow to keep the original PST unchanged while preparing selected emails for legal review?
