Make certain that you turn on Advanced Search Functions and check Hidden and
System files.
Next, search for the file name *.nk2.
The NK2 file is named as follows: <MS Outlook User Profile Name>.NK2.
Further, it is found in your Documents and Setting Folder.
(Make certain that in your Folder settings, you can view hidden and system
folders.)
Here's where you can look:
Docs and Settings\Your login user name\applications\Microsoft\Outlook.
For a utility that will let you open and edit the NK2 file, go to
