Microsoft OST To PST Converter Wizard is a specialized email recovery and mailbox conversion utility used to convert Outlook OST (Offline Storage Table) files into PST (Personal Storage Table) files. This process helps users recover inaccessible Outlook data, migrate mailboxes, create backups, and restore email information into Microsoft Outlook environments.
Microsoft Outlook stores mailbox data in different file formats depending on account type and synchronization mode.
