After installing a new Exchange 2010 sp1 setup, outbound mail is missing the 'Display Name' and is only showing the users email address instead of his display name. As far as I know it's default to show the DisplayName attribute, but this just isn't happening for any user even though the DisplayName attribute has been set. I've also checked the headers and there really is no mention of the display name. What could be the reason?

Can you make sure that dispaly senders name on messages is checked? EMC, org config, hub transport, remote domains, default, properties, format of original message tab.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thanks, that was it. I've never needed to fiddle with this setting as it was always on. Didn't even know it was there :) thanks!
