The transport rules that are available to Exchange Server 2010 allow you to do many things including adding a disclaimer to e-mails. The disclaimer message can be formatted using HTML code to give us more control over how the information appears.
In addition to normal HTML code, this text also supports inserting information from Active Directory fields of the mailbox account sending the e-mail. We can add this information by using the syntax: %%AttributeName%%, where Attribute name is the Active Directory attribute that we wish to display.
This means that we can use code similar the he code below to both add a disclaimer and provide an automatic auto-signature on any e-mails that we specify.
More details about this can be found at www.msexchange.org.
