4. Next, in the Export Outlook Data File wizard, select the OST file root folder you need, check the Include subfolders box and click Next.
5. Click Browse to change the default saving location, select the option to manage duplicate items as you need, and then click on Finish. In this way, you can convert OST to PST.
