Set wshObject = WScript.CreateObject("WScript.Shell")

strOLPath = wshObject.RegRead("HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\OUTLOOK.EXE\Path")

Set regx = New RegExp
regx.Pattern = "\d{1,2}"
set ma = regx.Execute(strOLPath)

strVersion = ma(ma.count -1) & ".0"

strCachePath = wshObject.RegRead("HKCU\Software\Microsoft\Office\" & strVersion & "\Outlook\Security\OutlookSecureTempFolder")

if (FsoObject.FolderExists(strCachePath)) then	'Check if the folder exists
	FsoObject.DeleteFile strCachePath & "*.*", True	'If the folder exists, then delete everything in it
end if

wscript.echo strCachePath
