Inovro

The product is a desktop utility that converts orphaned, corrupted, or inaccessible Microsoft Exchange OST files to PST and other formats, extracting mailboxes, attachments, calendars, contacts, and metadata while preserving folder hierarchy and headers. It serves IT and operations staff managing Exchange failures, migrations, or deleted profiles in businesses of all sizes, as well as individual Outlook users needing offline recovery. It runs as a client-side, offline application that performs read-only, low-level database scans without requiring an Exchange Server, Active Directory, or Entra ID connection.
