Best Way to Prepare PST Email Archives for Legal Discovery Without Outlook?

[henrywalker]

I'm assisting our litigation support department with preparing email evidence for a legal case. The client provided multiple PST files containing years of Outlook emails, but our review team needs everything in PDF format so attorneys can easily search, annotate, print, and share documents during discovery. The challenge is that not every workstation has Outlook installed, and manually exporting each email would require an enormous amount of time.
Another concern is maintaining evidentiary integrity. Every PDF must preserve the original sender, recipient, subject, timestamps, message body, and attachment references. Any missing information could create unnecessary questions during legal review. We also have to process thousands of emails within a limited timeframe, so efficiency is just as important as accuracy.
While searching for reliable ways to convert PST file to PDF, I realized that most free methods are only suitable for very small mailboxes. Large legal archives require something capable of processing entire folders while keeping everything organized and intact.
One solution I found was the DRS Softech PST to PDF Converter For Law Firms. Based on its documentation, it supports bulk conversion, selective export using date filters, preservation of folder hierarchy, preview before conversion, and exports without requiring Microsoft Outlook. Those features seem particularly valuable for law firms handling eDiscovery requests, compliance audits, or client record retention.
I'd love to hear from legal professionals, compliance officers, or IT administrators who have managed similar projects. What workflow has worked best for converting large Outlook archives into PDF? Were there any unexpected issues during the conversion process, and what practices helped ensure complete, court-admissible documentation without risking data loss?
