The files are stored in a .PST file located in your user folder. The
default location is C:\Documents and Settings\<username>\Local
Settings\Application Data\Microsoft\Outlook. Note that these are hidden
folders, so you'd need to enable the viewing of hidden folders and items.
To do this in XP:
- Open My Computer.
- Click on Tools -> Folder Options.
- Click on the View tab.
- Check the box to "Show hidden files and folders"
Other handy things that may be present in the above location is a .PAB file
(the personal address book) and a .NK2 file (the nickname cache which allows
you to start typing letters in the To: field and it autocompletes for you).
