I recommend using eSoftTools Outlook PST Recovery Software to open and import PST files into Outlook 2010. It's easy to use. You don't need to open Outlook to repair the pst file. It shows a preview of the conversion email in real-time. The demo version is available to all users. With the demo edition, you can convert 25 emails in each folder and have access to support services that are available 24 hours a day, seven days a week.
