Opens my Outlook archive files fast without Outlook installed. Clean interface, straightforward preview and export functions. Everything works locally on my Mac. Exactly what I needed to check old email backups. ### 1/5 — Unterordner gehen nicht zu öffnen *2026-07-03* Das Programm kann die PST Datei öffnen, wenn dort allerdings Unterordner angelegt wurden, werden diese nur mit einem Pfeil (rechts) angezeigt, können aber nicht aufgeklappt werden. Schade, somit komme ich nur an wenige Mails und das Programm ist für mich nur Schrott. **Developer response:** Vielen Dank für Ihre Rückmeldung und den Hinweis. Wir haben das Problem mit den Unterordnern inzwischen geprüft und behoben. Bei bestimmten PST-Dateien konnte es vorkommen, dass Unterordner zwar angezeigt wurden, sich aber nicht aufklappen ließen. Mit der aktuellen Version ist dieses Problem behoben und die Unterordner sollten sich wieder wie erwartet öffnen lassen. Bitte aktualisieren Sie die App auf die neueste Version und probieren Sie es noch einmal aus. Falls dennoch etwas nicht wie erwartet funktioniert, schreiben Sie uns gerne an admin@yenpi.com – wir kümmern uns darum. Vielen Dank, dass Sie uns mit Ihrem Feedback geholfen haben, die App zu verbessern. ### 5/5 — Perfect Standalone PST Viewer! *2026-06-04* This app is a lifesaver for opening old Outlook .pst files without having the actual Outlook software installed. It is incredibly fast, clean, and does exactly what it promises. ### 5/5 — Perfect PST Viewer! *2026-05-28* Reliable, Fast and Simple, Work as I Expected! **Developer response:** Thank you so much! ### 3/5 — Converts PST to MBOX but clunky *2026-05-27* After conversion, the newly created MBOX file doesn’t appear to be loading in Apple email. However, it turns out that the folder of interest is buried several levels deep, but the emails are there. Also, link to support connects to email but doesn’t seem to get any response from the author. **Developer response:** Thanks for reporting this, and sorry for the inconvenience. We were able to quickly identify the cause and have already released a fix. Please try again with the latest version when you have a chance. In some cases, Apple Mail places the imported folder several levels deep in the mailbox hierarchy, but the emails should be there. We've also replied to your email with additional details. If you run into any further issues, just let us know—we're happy to help. ### 5/5 — The best PST viewer app！ *2026-05-25* Works very well！ ### 5/5 — Super simple and quick！ *2026-04-22* very good app， works very fast！ ### 5/5 — Search actually works! *2026-04-20* I tested this with a 3.7GB MBOX file.
