How do I send email from an MS Exchange account so that the From name is something more descriptive. For example, I regularly get email from AT&T which displays messages from "AT&T Account Manager" (firstname.lastname@example.org). I would like to send our mail messages from email@example.com but have the From field display as "My Company Bank & Trust". How do I set up the MS Exchange / Active Directory account to do this? I have tried the obvious, like changing the Display As field, but it doesn't seem to make a difference.
