Microsoft Outlooks AutoPreview lets you see just the first three lines of messages. Chilton Preview adds a message preview window to Microsoft Outlook displaying more: the contents of the currently selected message, header information, attachments, and the To: and Cc: recipients. Internet and email addresses are highlighted in blue within the preview window and can be clicked to launch either a browser or new mail message window. File attachments can be opened or saved when applicable. Customization of the preview window is also possible.
