How can I convert an OST file to PST format when Outlook cannot open the OST file?

When Outlook cannot open an OST file, it usually means the file has become inaccessible or orphaned. In such situations, converting the OST file into PST format is the best solution. A reliable tool like the PDS OST to PST Converter can help users recover emails, contacts, calendars, and attachments from the OST file and export them to PST format. The software performs a deep scan of the OST file and safely converts the mailbox data while preserving the original folder hierarchy and email properties.
