Stellar Repair for Outlook is a specialized Windows utility that repairs corrupt or damaged Microsoft Outlook PST files and restores complete mailbox data with full integrity. It goes well beyond Microsoft's built-in Scanpst.exe tool, handling large PST files and custom folder structures that the native repair often fails on. Built for both everyday Outlook users and IT support teams, it recovers emails, attachments, contacts, calendars, tasks, notes, and journals, then lets you save the recovered data to a new PST or export it to formats like EML, MSG, RTF, HTML, and PDF. Higher editions add direct export to Microsoft 365 and Live Exchange, making it a practical fit for helpdesk and desktop support workflows.
PST Repair Engine rebuilds severely corrupt and oversized PST files that Scanpst.exe can't process. Mailbox Recovery restores emails, attachments, contacts, calendars, tasks, notes, and journals while preserving the original folder hierarchy. Export & Save outputs recovered data to PST, EML, MSG, RTF, HTML, and PDF, with cloud and Exchange targets in higher editions.
