PST Walker vs Stellar Converter for OST

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.
