We have Exchange 2003 Std SP2 and running OMA and OWA from same server for those mobile push mail users and business travellers. Recently, our mobile users cannot access push mail from their E61 nokia phone with Mail for Exch 2.7 and always prompting account is invalid.
So my issues here are 1. OMA is not accepting domain account and keep pop up with pw request. 2. OWA is can go in but right panel shown loading... message and error on page with IE left hand corner.
