Tif opening problem in Outlook

If you are using win xp pro and outlook 2003 and can't open Tif files in outlook.

Go to:
C:\Documents and Settings\username\Local Settings\Temporary internet Files\olk xxx
then delete this library contents.

if you cant see this library - open the hidden files and folder in the folder option

Now restart the computer to normal mode, open the outlook
and open the tif files

To locate temporary internet files you can follow as below.

Open REGEDIT.EXE and go to Edit -> Find... In the Find dialog box type "OutlookSecureTempFolder" without the quotes and locate that registry key.

That key will contain the actual folder location, and will look like:
C:\Documents and Settings\%USER_NAME%\Local Settings\Temporary Internet Files\OLK#\ (where # is a random letter or number)
