Schade, somit komme ich nur an wenige Mails und das Programm ist für mich nur Schrott. **Developer response:** Hallo Seven-67, vielen Dank für Ihr Feedback. Es tut uns leid, dass Sie Probleme beim Öffnen der Unterordner in Ihrer PST-Datei haben. Wir möchten das Problem gerne untersuchen und Ihnen weiterhelfen. Bitte kontaktieren Sie uns unter admin@yenpi.com und teilen Sie uns weitere Informationen mit (z. B. Ihre Systemversion und Details zur PST-Datei). Vielen Dank für Ihre Unterstützung. ### 2/5 — Can’t export by date range *2026-03-30* Can’t export by date range. Link to support doesn’t work. Waste of money. **Developer response:** Hi Mr. Cote, Thank you for your feedback, and I’m sorry for the inconvenience. We’ve now added date-range export and submitted an update to the App Store — it should be available soon after approval. Regarding the support link, it works in our region, but if you’re unable to access it, please feel free to contact us at admin@yenpi.com — we’re happy to help. We appreciate your feedback, and if the update resolves the issue, we’d be grateful if you’d consider updating your review. — PST Viewer & Converter Team ### 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 — 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.
