What is the easiest and fastest way to repair my Outlook.pst Outlook 2007?

Scanpst.exe does not work. I have tried a number errors, such as, "Can not start Microsoft Office Outlook. can not open the Outlook window. The set of folders can not be opened. have been detected errors in the file. "Quit Outlook and all mail-enabled applications an unknown error occurred, error code: 0x80040600 You can not delete this file Outlook data. configuration information in the file is being copied to the new data file standard. you can delete the file after this information is copied .. Very stuck and confused:)

Remove Outlook. Reinstall it. (I look for a virus first, however.)
