Stellar Converter for OST helps admins extract all mailbox data such as emails, attachments, contacts, calendars, tasks, notes and journals from OST files, even if inaccessible for Outlook, and ingest that data into a live Exchange server or Exchange Online mailbox, or convert it into PST or other formats. This can be helpful if, for example, a mailbox was deleted and all we have is the OST as the EDB is not available, or if we have an OST for a mailbox from an old non-Exchange system that is no longer accessible. With this tool, we can easily convert any OST file to PST.
