Hi emkwan
You can try a tool called Advanced Outlook Repair. You can download a
free demo version at [url]http://www.datanumen.com/aor/aor.exe[/url] . I think
it is a useful repair tool for you. It is easy to recover your PST
file by using its wizard. It is a powerful tool to recover messages,
folders and other objects from corrupt or damaged Microsoft Outlook
PST files.
