There are 2 places you could be referring to. The ones that auto fill when you are filling out a form in a browser or when you are trying to send an email.I assume you are talking about those for email.Most likely you will find them in the address book for your mail client like Gmail, Yahoo, Outlook or what ever you may use. Getting to these is a bit different. Not all addresses may go here either unless you added them manually. Provide more details on what you are using for your mail client.
