Exchange 2007 to 2013 Issue

Hello,
I am migrating a client from Exchange 2007 to Exchange 2013.  I have everything setup to Coexist.  I have move a few test mailboxes over from Exchange 2007 to Exchange 2013.  When I open Outlook I am continually prompted for the username and password.  I have tracked this down to the public folder still located on the Old Exchange 2007 machine.  Does anyone know how to resolve this where the public folder can exist on the Exchange 2007 machine while we are migrating mailboxes.

Thanks for your help
Jason

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
