You can find ScanPST.EXE in the C:\Program Files\Microsoft Office\Office12
directory. Run it and follow the prompts to check the structure of the PST
file in question.

Can you navigate to the PST file's directory from Windows Explorer? Seems
odd that the path wouldn't be valid. I'm guessing, possibly incorrectly,
that the external hard drive is directly connected to the PC running
Outlook.

How do I do ScanPST.EXE?
The error message is that the path to the archive is not valid.
