a.. Make sure you include hidden and system files and folders when
searching for pst-file
b.. By default it is located in
C:\Documents and Settings\%username%\Local Settings\Application
Data\Microsoft\Outlook\
For Windows Vista the default is
C:\Users\%username%\AppData\Local\Microsoft\Outloo k\
c.. You can also locate the file by using
Rightclick the root folder (probably Outlook Today)- Properties- button
Advanced- field Filename

I have a laptop that had Vista Ultimate installed on the C drive and Office
2007 setup on the D drive. the C partition was formatted and I need to
recover the mailbox from Outlook 2007. I cannot locate where Outlook keeps
the Mailbox files. I see it talks about PST files but even on my own
system I
cannot locate a .PST file using the same setups.
I have looked inside c:\users\*username*\*.pst and found no PST files at
all. I have searched the C and D drives for *.pst and found nothing.
I am looking at my own functional laptop and cannot find the default
location where Outlook 2007 keeps mail, contacts and such.
Can anyone help?

Do you ever wonder why the only thing common in all your dysfunctional
relationships is YOU?
