Outlook 2010 - Undeliverable addresses flagged and shaded in blue?

When I enter a bunch of addresses into an addressee field in Outlook, some of the undeliverables were shaded in blue.
Question:  How can I extract those undeliverable names.  I see that there is a way to "X" them out but I want to extract those names and place them in a file.
