Apparently, all versions of Windows and Microsoft Office ship with an Outlook .pst repair tool called scanpst.exe.
To find scanpst.exe on your system, use the Search command from the Start Bar.
Select the Run command on the Start bar and type in scanpst.exe (make sure Outlook and Outlook Express are not running when you do this).
Scanpst.exe will report if it can/has recovered files. Open Outlook/Outlook Express and rename the recovered files.
If your PST files were not recovered, run Scandisk and then run scanpst.exe again.
