Some of my clients would like to have the auto-complete for addresses in the "To" field go based on last name. I figured out that by changing the "Display As" field in the contact form I could get this to work, however, there are hundreds of contacts being carried over from a previous email client with this upgrade. is there a fast way to change this on all the contacts without editing each individual contact? A code of some kind or an option I could change either in the Outlook application or the Server itself??
