In their own words
PST Walker
PST Walker is a Windows program for opening Outlook PST, OST, MSG, and EML files without Outlook, with tools for recovering deleted items and folders. It searches Outlook items by keyword, Boolean queries, filters, and recent searches. Users can export or convert items to PST, MBOX, MSG, EML, and CSV formats. Recovery includes deleted or purged emails, contacts, and calendar entries, as well as Outlook Rules and Alerts. The maker says conversion processes files locally without uploading file data to its or third-party servers. A free demo limits export to 15 emails per folder; the full version allows unlimited export. The listed Lite License costs $32.95 a year, Pro costs $64.95, paid once, Business $99.95, paid once, Technician $169.95, paid once, Standard $249.95, paid once, and Floating $449.75, paid once. Enterprise pricing is custom. Licenses are one-time purchases without automatic recurring charges, though maintenance expiration ends updates and support for perpetual licenses. Supported systems include Windows 11, 10, 8.1, 7, and Windows Server 2012–2025, with.NET Framework 4.7.2 or later required.
Stellar Repair for Outlook
Stellar Repair for Outlook is desktop software for repairing corrupted Outlook PST files and recovering mailbox data. It can recover emails, attachments, contacts, calendars, tasks, notes and journals, including deleted items, which it marks in red. Users can preview recoverable items and filter emails before saving. The maker says it handles PST files of any size, including encrypted or password-protected files, and works in read-only mode so the original PST is not modified. Recovered data can be saved as PST, EML, MSG, RTF, HTML or PDF. A licensed Microsoft Outlook installation is required to complete desktop repair and save to a new PST. The desktop trial can scan and preview items but cannot save recovered data; desktop use requires 64-bit Windows 11, 10, 8.1 or 8 and at least 8 GB of memory. A browser-based service is also available without local installation. The free online plan covers one PST up to 500 MB with a download available within 24 hours; Premium costs $29.99, paid once per file for one PST over 500 MB and up to 5 GB, with a 48-hour download window.
