New Outlook 2007 preview handlers are constantly being developed. If you click an attachment and the extension isn’t associated with a preview handler, you’ll see a message in the preview pane that says “This file cannot be previewed because there is no previewer installed for it.” You’ll also see a link that you can click for more information about Outlook 2007 preview handlers.
