I am accessing my Comcast email through Outlook 13. When I save a new email address to the Outlook address book, and then I open a new email and type the first few letters of the email address I previously saved, Outlook is supposed to automatically fill in the rest.

It does this with some of my email addresses, but it does not recognize other addresses in my contact address book. I can't figure out why it will recognize the email address of some but not others.

Thoughts? Jake
