UniSA's Global Address List (GAL) updates itself at 5:30am ever morning. If you are needing to email an address which was only changed today and are unsure of the new (either recently changed or created) email address to type manually, you can select an ‘All Address Lists’ folder (All Contacts, All Distribution Lists, All Groups, All Rooms and All Users – depending on what category you are after) for a live copy of data available in the Exchange GAL and then search for desired address. The following day the GAL will update itself and you should not have to do this for the email address again.
