The safest method to convert OST to PST in Microsoft Outlook is to use built-in features inside Microsoft Outlook such as the Import/Export wizard or AutoArchive, provided the OST is connected to an active Exchange or IMAP account. In Outlook 2016/2019/365, go to File > Open & Export > Import/Export, choose “Export to a file,” select “Outlook Data File (.pst),” and then choose the mailbox folders to export. This method preserves emails, contacts, calendars, and attachments while minimizing corruption risk. It is safer than third-party converters because it keeps data within Microsoft’s native environment and avoids malware or data loss risks. For disconnected or orphaned OST files, the safest approach is to reconnect the original account or use Microsoft-supported recovery via Exchange or Microsoft 365 admin tools. Third-party Aryson OST to PST Converter tool should only be used as a last resort when Outlook cannot access the mailbox data. Always back up data before performing any conversion to prevent loss issues safely recommended.
