For this you will need to upgrade your Outlook 2003 version to Outlook version 2007. You can get Microsoft Office 2007 for that. Microsoft Outlook 2007 has a preview attachment features. Buy this you can preview the attachments without saving it. You just need to click on the attachment and it shows in the reading pane. There are not settings or extra addons for this.
