@sunny20 You definitely can change the body of the message for a particular customer in normal Desktop, so I can't imagine why you wouldn't be able to in Enterprise.
There is a common error people make when sending out more than one e-mail at a time, though.
That is, they do not click on the line for the customer they want to edit the body for. Could be that this was the case for you; if so, somebody else got that message instead.
