computer removed from domain, .nk2 file still available in account?

AE_JB used Ask the Experts™
A computer contracted malware and was removed from the domain and added to a work group as part of the remediation process.  
The user had many contacts in her autocomplete field of Outlook 2007.  I am able to navigate to the user's folder through the local administrator account, but there is no .nk2 file.  Hidden files and folders are visible.
I do not see any file with a .nk2 extension, only files with .DAT, .OAB, .KFL
Is there any way to recover the autocomplete information?

Yes it should be there. Do a search for .nk2 and include hidden folders.
Here's where you should be looking for that file:

If you don't find it there, might be worth trying a free undelete program, just to see if there's enough of a fragment left to salvage.

Removing a computer from a domain won't remove any files from the computer, so you are either looking in the wrong place, or the malware / malware removal may have removed it.

You sure the user was using Outlook 2007?

If they were using Outlook 2010, you wouldnt see an NK2 File

It would be an Stream_autocomplete.dat file in C:\Users\%username%\AppData\Local\Microsoft\Outlook\RoamCache


It's not there.  Thanks for the info on how to locate it, and options for recovery.  I'll see about an undelete program for recovery.  Good to know the changes between Outlook 2007 and 2010 with regards to autocomplete.
