Did you know that you can remove names from the list of nicknames that pops up when you start typing someones name into the TO field (or CC or BCC)? Maybe someone pops up that you don’t email anymore or worse yet you entered someone’s email wrong one time and it keeps showing when you start typing in their name or email address. 

To delete a name from the cache:

• When you’re in a new email, start typing the name or email address until it shows up in the list. This “nickname” list can be browsed by scrolling up or down through the list.
• To delete the name just highlight the name you’re wanting to remove and press the Delete key.
