This tiny application lets you put classification labels on e-mail messages sent via Microsoft Outlook, but it fails to improve upon the existing sensitivity options already available in Outlook. Message Classification adds a toolbar in the window as you create a new message window, allowing you to label individual messages as Unclassified, Confidential, or Secret. Unlike the sensitivity options, the labels don't impact recipients' ability to manipulate the messages. Also unlike Outlook's existing importance icons and follow-up flags, the classification label is added only in the body of the message in the trial. (The full version promises to add the label in the e-mail header and the message subject line and allows customization of labels.) It does what it promises, but given what Outlook already brings to the table, we don't predict many users will get excited about Message Classification.
