very good app， works very fast！

I tested this with a 3.7GB MBOX file. Searched for a word from an email 8 years ago. Found it in under 2 seconds. That alone deserves 5 stars. Plus dark mode, and attachment previews. Amazing work."

I recently had to access several years' worth of old Outlook archives, and this app handled the task perfectly. The interface is clean and native to macOS, making it incredibly easy to browse through folders and view attachments without needing Outlook installed. The conversion process is lightning-fast—I was able to bulk-export thousands of emails to PDF and EML formats with zero data loss or formatting issues. If you need a reliable way to manage or migrate PST files on a Mac, this is hands down the best tool on the market. Highly recommended!
