One of my contacts changed his e-mail address. When he sent me a new e-mail, I clicked on the button for Outlook to save the new address. It saved it as a secondary address. I then changed the primary address, as the old one is no longer any good. But I cannot get rid of the secondary address; every time I erase it, Outlook puts it back. The contant shows up twice in the contact list, both addresses being the same. How can I convince Outlook that the contact has only one address?
