Outlook has a useful feature called the Automatic To-List. The way it works is that when you type an email address into the To field of a new message window, the next time you want to send a message to the same person you don't have to retype the address--just enter the first few letters of the address (or the person's name) and you'll see a choice of possible addresses (or names) you can choose from.
Unfortunately, if you type a mistaken email address into the list it stays in there, cluttering up the list. But there's a way you can remove addresses (or names) from this list--just display the list, use the down arrow key to highlight the name you want to delete, and press the Delete key on your keyboard.
