Exchange 2007 to 2013 Mobile Phone Issues

I am currently migrating from 2007 to 2013.  I am moving mailboxes and have both servers coexisting.  I moved my mailbox last night and when I woke up my phone automatically changed to the new server address and was receiving mail no problem.  My issue is I cannot send.  I receive an undeliverable.  If I am connected internally via outlook I can send and receive inside and out no issues.

What am I missing?
