Yep. You have to change it in the registry. You can create a text file with the name: Office_Security and then change the extant ion to: reg. Right click on it and select edit. Copy what I've send to it. You can add other extension if you like with ; between the extensions. When you finish edit close it and keep the changes. By double clicking it will update your registry. Or you can manually add it to the registry in the location specified. You run it on computers where outlook is installed.
