Hi, In a migration from Exchange 2003 to 2007 SP1, we want to use the new Exchange 2007 CAS servers to give users access to their Exchange 2003 or 2007 Mailboxes, it works well when mailboxes are on 2007, but not well when mailboxes are on 2003. The interface is all messed up and full of squares, no error messages though... We are checking permission or authentification mis-match, but just wondering what else can cause this... Thanks !!!
