DataNumen Outlook Repair is Windows software for repairing corrupted Microsoft Outlook PST and OST files. It is intended for individuals, IT teams, investigators, and organizations managing damaged or inaccessible Outlook archives. The software can recover messages, attachments, contacts, calendars, tasks, notes, folders, and deleted Outlook items, while producing repaired PST files compatible with supported Outlook versions. Its scope suits recovery work that goes beyond a single damaged mailbox file.

Its strongest fit is comprehensive Outlook file repair. Alongside PST and OST repair, it supports batch repair of multiple PST files, oversized and password-protected files, and recovery from disk images, backups, and temporary files. It can also convert between supported Outlook PST formats, split output PST files, and rebuild folder hierarchies in repaired files. These capabilities make it relevant when the recovery task involves several files, difficult source conditions, or a need to preserve mailbox organization.

The product fits environments centered on Microsoft Outlook and Microsoft 365, but its platform scope is Windows. It is a paid product, with licenses organized by user ranges from 1 user through 500+ users; the 1-user plan includes a single-user license. A free demo download is available, but there is no time-unlimited free plan. Choose DataNumen Outlook Repair when PST and OST recovery breadth, batch work, deleted-item recovery, and archive reconstruction matter. Choose another tool when MBOX output or a non-Windows platform is required.
