I’m dealing with several PST archives collected from different Outlook installations, and I need to review their contents before deciding what should be retained or exported. The problem is that Outlook isn’t installed on the current system, and one of the PST files is quite large while another appears to have issues opening normally.

I don’t want to make changes to the original archives just to inspect them. Ideally, I need a read-only method that lets me check emails, attachments, contacts, calendars, and other mailbox items while preserving the original data. I came across SysInfo PST Viewer while researching this because its product information says the viewing process does not overwrite, modify, or delete the original PST file. It can also work offline, which is useful when confidential email archives should remain on the local machine.

The search and preview capabilities are also important for my situation. Instead of manually opening hundreds of folders, I’d prefer to search by From, To, Subject, date range, or attachment status and then inspect the relevant messages. The viewer also provides access to message headers, MIME data, raw HTML, notes, attachments, and other email details, which could be useful for audits or older business archives.

I’m particularly curious about using a PST file viewer for oversized or partially corrupted archives. The product page mentions support for oversized and minorly corrupted files, as well as healthy, orphaned, blank, and password-protected PSTs. It also supports ANSI and Unicode formats and Outlook files created across older and newer Outlook versions.

For me, the biggest advantage would be being able to open PST file without Outlook and inspect the archive before taking any further action. If the required emails are found, I could then decide whether to export them to PST, EML, MSG, MBOX, PDF, or CSV, depending on the use case. The product page also mentions selective date-based exports, duplicate removal, attachment handling, and skip/resume functionality.

Has anyone here handled a similar PST archive situation? Would you recommend previewing and filtering the data first before exporting it, especially when working with very large or older Outlook PST files?
