What PST Walker is
PST Walker is a Windows program that opens Outlook PST, OST, MSG, and EML files without Outlook and can recover deleted items and folders. Search tools include Boolean queries, keywords, filters, and recent-search history. It can export or convert Outlook items to PST, MBOX, MSG, EML, and CSV formats. Recovery covers deleted or purged emails, contacts, calendar entries, and Outlook Rules and Alerts.
