Thank you for the warm welcome. I hope to visit this site more often.
Yes, NTDOC, it worked perfectly. I appreciate the advice on having the script check the wildcard as the nk2 file does depend on the profile name. I also added a preliminary check so I didn't turn this into a loop:

Dim $NK2
$NK2=ReadValue('HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders', 'AppData')
If Exist($NK2+'\Microsoft\Outlook\*.old')
QUIT
EndIf


Many thanks,

John
