Good morning,
I was referred from http://community.office365.com/en-us/f/158/t/261575.aspx and was hoping you would be able to assist me with the inquiry below. Thank you!
When creating a new user mailbox, the Display name defaults to "First name, Initials, and Last name" (as confirmed by http://technet.microsoft.com/en-us/library/jj991919(v=exchg.150).aspx). More specifically, the default is "First name, SPACE, Initial(s), PERIOD, Last name". Our Exchange 2010 environment is presently configured to format new mailbox display names to "Last name, SPACE, First name, SPACE, Initial". We are in the process of testing Exchange 2013 for migration from Exchange 2010 with existing mailboxes of 5,000+ and need to configure Exchange 2013 to default the display name utilizing the same format as established through Exchange 2010. How can this be accomplished?
Seth
