If you have put the person in you Contacts list, use the nickname for their name and in Options / Email Options / Advanced Options make sure "Automaeic name checking" is checked. Then, when you put a name or partial name in the To: box and LEAVE the To: box, Outlook will check the Contacts list for that person or persons whose first or last name begins with the letters you typed into the To: box. SInce it checks for partial matches, you really don't have to use nicknames. IE: Fr will find Fred.
