Disclaimer for Outlook® is a versatile tool to automatically format outgoing email. You don't need Exchange or any other mail server to add the signature and disclaimer because it is a client-based tool (outlook com add-in). This means that you actually see what you sent out. This is not the case with server-based tools.

The message processing is done on the client-pc, but the network administrator can administer the settings with one central ini-file on a file server. Even Exchange mailbox properties or Active Directory fields can be used in the text. You can even use html formatted data stored in the active directory fields. This way you make sure that everyone uses the same centrally stored disclaimer, Company Logo, signature and layout for every e-mail they send. You can even run advertising campaigns or advertise your upcoming events with hyperlinks that point to your web server in every email that (some or all) users send out.
