1. Enter one or more characters in the To, Cc, or Bcc boxes. Then in the Auto-Complete List that appears, select the unwanted suggested recipient by using the arrow keys or by hovering your mouse over the name you want to remove.
2. Click the cross or press delete
TIP: Once a recipient name is removed, it won’t appear again in the Auto-Complete List unless you deliberately select it from your Contacts list or type the address in manually. These actions will add the address to the Auto-Complete List again. If you want to permanently remove a recipient from your Contacts list, see delete a contact.
