I am running Exchange server 2010. I need to make sure that all of our outgoing emails have a “confidentiality disclaimer” at the bottom of each email. I know it can be done through users signature but that means I have to set up 150 users, and then when user leaves and new one set up I have to do it all over again. In the past (before the upgrade from 2003 to 2010) I used GFI email essentials for SPAM control and they had this awesome feature where it would automatically stamp every outgoing email with the any message I want (so I used it for a disclaimer)
is there anyway it can be set up the same way anywhere on Exchange 2010 ?
