Additional Information

Question: How do you set the "Display Name" (from) to show the name instead of the email address on iPhone?
This is a limitation of how Exchange ActiveSync is implemented in iOS. By default, iOS takes the email address and uses that. There's no way to modify it presently so that a friendlier display name shows on an iOS device.
