After adding an Exchange account to an iPhone or iPad, contacts in the Global Address List do not have a Display Name.
For instance when adding recipients to a new message, contacts from the GAL will display but email address only with "No Name" where the contents of the Display Name field would typically be located.
Also in the Contacts app, when navigating to the Exchange Global Address List via "Groups" no display names appear. However if I start typing in the search field I get a short list of contacts but again email addresses only, no display name.
Is there any way to get the Display Name from the GAL to display in iOS?
