I have a 2008 R2 domain. I am using Exchange 2007 ( Which I am not familar with much ) My global address list displays first name - Last Name. There was a way in Exchange 2003 to change the display names. How can I change Exchange 2007 GAL to display last name first? Thanks in advance for your help.
