Perfect Standalone PST Viewer!

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.

Thank you so much!

Converts PST to MBOX but clunky

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.

Response from developer

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.

The best PST viewer app！

Works very well！
