BitRecover OST to PST Converter is a powerful Windows utility designed to extract mailbox data from Outlook OST files and save them in PST (Personal Storage Table) format. It ensures complete data recovery from corrupt, orphaned, or encrypted OST files — including emails, attachments, contacts, calendars, tasks, notes, and journals. Once converted, you can easily import the resulting PST file into any version of Microsoft Outlook (including Outlook 2021, 2019, 2016, 2013, and older).
