Do you have to change all your contacts individual or is there a way to change them all at once. I have the correct setting under Email options but it show send in RTF under their individual contact.

In addition to checking the mail format, you need to double click on the address in the contacts and make sure they are not set for RTF.
Are all addresses affected or just some? if just some, when you begin to type their address and it comes up, use the arrow keys to select it and press Del to get rid of it. Select their address from contacts and see if it works better.
If all addresses, does it happen in safe mode? To open Outlook in Safe mode: Close Outlook then hold Ctrl as you click on the Outlook icon. You'll get a message asking if you want to start in Safe mode. Click Ok.
