If you’ve ever dealt with a corrupt OST file, you know how frustrating it can be — especially when Outlook refuses to open or crashes repeatedly. I recently faced this exact issue with an orphaned and corrupted OST file from a client’s old PC. After trying a few manual tricks (scanpst, profile recreation, etc.) with no success, I looked into third-party tools.

That’s when I came across the ATS OST to PST Converter, and honestly, it saved the day.

Here’s what made it work so well:

✅ No Outlook Required – Unlike some tools, ATS doesn’t rely on having Outlook installed. This was a huge plus since the client’s Outlook installation was broken.

✅ Recovered Corrupt Data – The tool scanned and repaired the OST file, allowing full access to emails, attachments, contacts, calendars, and even deleted items.

✅ Simple UI, Fast Results – It only took a few clicks to scan and convert the file to PST format. The interface is clean and easy to follow.

✅ Preview Feature – Before conversion, I could preview all mailbox items — helpful for confirming the file was fully recovered.

✅ Multiple Export Options – Besides PST, it also offers MBOX, EML, MSG, HTML, and even Office 365 export options.

If you’re stuck with a damaged OST file and need to get it into PST without relying on Outlook, ATS OST to PST Converter is a reliable and efficient choice. I highly recommend trying their free demo version to see how well it works before committing.
