When you are using Outlook to email someone and you go to put there email address in and that list of past email pops down.  I was wondering if anyone new if you could erase it.

After you start typing, the menu of names will appear and one of them will be highlighted. Use the up and down arrow keys to select the name you want to delete, then type the "Delete" key to remove that name from the list. You can repeat this for all the names you want to delete. 

Note that I just happen to know that because we Program Managers at Microsoft use Outlook A LOT :-)
