Setting problem, halt Auto Resolve feature in Outlook 2010

I am searching for an answer to halt Auto Resolve feature in Outlook 2010.
I have obtained 1000 contacts in my folders and several of them have no email address adjoined.
So, when I make a New Email and chose 300 contacts and send it, Check Names windows pop ups for every contact without email address.
Is there any setting in Outlook 2010 immobilizing the utility at all?
Please guide me on this dilemma
