The right PST viewer depends on what you need, but a few things matter for most people. It should open PST files without Outlook, handle large or damaged files, and leave your data untouched. Password-protected files are also worth checking for, since old archives often have them. Support for both ANSI and Unicode PST files is a plus if some of your files are from older Outlook versions.
Kernel PST Viewer is a free option that covers these points. It works without Outlook or any email client, and it opens healthy, orphaned and corrupted PST files, including files damaged by the old 2GB size limit. It can preview password-protected files even when the password is unknown. There's no file size limit, and you can load multiple PST files at once and search across them with the Find option, using subject, body, sender, recipient, date or attachment details. Your folders appear in the same layout as in Outlook, and you can read emails, attachments, contacts, calendars, tasks, notes and journals. It also creates a file analysis report with graphs of item types and mail flow by date and sender.
