Converting an OST file to PST in Outlook 2019 can be a bit tricky, especially in 2025, since Outlook itself doesn’t provide a direct export option for orphaned or inaccessible OST files. If your Outlook profile and Exchange account are still active, you can use the built-in Import/Export wizard to export mailbox data into a PST file. But this method works only when Outlook is properly connected to the server. In cases where the OST file is orphaned (for example, if the Exchange account is deleted or inaccessible), Outlook won’t let you open or export it, which can be frustrating.

That’s where a dedicated tool like eSoftTools OST to PST Converter Software comes in handy. This software allows you to open and convert OST files to PST even without an active Outlook or Exchange connection. You can recover emails, contacts, calendars, attachments, and other mailbox items while keeping the original folder hierarchy intact. It also provides multiple export formats like EML, MBOX, Office 365, and more, giving flexibility beyond PST. For anyone in 2025 dealing with old or orphaned OST files, using such a reliable solution saves both time and stress.
