Is There Any Reliable Tool to Convert Corrupted OST Files to PST?

Finding a trustworthy solution to convert OST to PST becomes difficult when the OST file is corrupted or inaccessible. I faced a similar situation after a sudden system crash damaged several Outlook OST files connected to an old Office 365 account. Outlook could no longer open the mailbox, and manual export methods completely failed because the Exchange profile was unavailable. After testing multiple utilities, I finally used Aryson OST to PST Converter, which successfully recovered and converted the corrupted OST files into PST format without losing any mailbox content. The software extracted all emails, attachments, contacts, tasks, calendars, journals, and deleted items while maintaining the original mailbox structure and metadata. The tool allows users to convert OST data to PST and many other file formats like MBOX, PDF, CSV, DOC, HTML, and several other formats. Along with this, the direct migration option allows users to transfer OST emails to Gmail, Office 365, Thunderbird, Yahoo Mail, IMAP servers, and Exchange Online. Moreover, the software supports all versions of Windows, Mac and Linux OS.
