I know this the wrong group but I need Hotmail help

Sorry to post here I know it's not specifically for Hotmail but I
couldn't find any group with Hotmail in the title.

I am trying to remove an address from the auto complete list. The
address no longer exists in the address book but it still comes up as
a choice when I type the frist few letters of the new address.

Where is this information coming from and how do I get rid of it?

Thanks in advance to all who reply.
