I set Simple Display Name for my account to a test value. HKLM\SYSTEM\.........\ParametersSystem\Use Simple Display Name was set = 1. Exchange restarted. I sent an external email and it displayed my test simple display name (expected). A collegue, whose Simple Display Name had been left blank, sent an external email. His email displayed his Account->User logon name (unexpected) rather than his General->Display name (expected). My expectations had been set from a post on tech-archive.net Purportedly from Robert Li(MSFT) Microsoft CSS Online Newsgroup Support which said ".... For external emails, we will see the Simple Display Name" "for Sender. Only if the Simple Display Name has been " "configured, the Information Store will use it. Otherwise, it will " "use Full Display Name." FINALLY, the question Is there a means by which the General->Display name will be displayed in an email sent by users whose Simple Display Name is left unconfigured??. cheers shane

Hi, The explanation from Robert Li is the standard answer on this issue. Until now, there is no any way could achieve your needs. Thanks Allen

hi Allen, So are you saying that when Robert says "Full Display Name" he means "Login name" not "Display Name"? cheers shane

Hi, Of course, the Full Display Name means Login name. For the user who left the simple display name as blank, it will take the display name from its Logon name rather than Display Name. So far, there is no any feasible work arounds to resolve this issue. Thanks Allen

Of course, it sounds silly -but I accept thatto bethe way it is and Ithank you for your feedback in defining it. cheers shane
