Outlook - My Outlook '07 .PST file is not in the normal location - Where is it?

The hard disk crashed on my daughters Vista Laptop. I have pulled the disk and can access it via a disk recovery utility on my desktop. I have copied off all important data EXCEPT for her Outlook 2007 data. The .PST file is not in the normal users/%username%/AppData/Local/Microsoft/Outlook/ folder and I can not search the disk to find where it might be. Is there an Outlook configuration file I can get to (in a known location) that will tell me where the .PST is stored? Or are there any other locations it is likely to be at? Or any other ideas please? I really really need to get her Outlook data off the disk. Thanks in advance.

If it isn't there, then someone changed the path of where the .pst file is stored.  The path can be changed in Outlook via the Account Settings/Data Files tab.

Is there a reason you can't just restore the entire hard drive to a external hard drive?  Then, you could perform your search.

These threads hint the location could be stored in the Registry -
