Hi all We use win2K3 and Exchange2K3 : 1. How I can show size attachment at OWA? 2. After update pacth SP1 for Exc2K3, why we can login only create user name and password, but we must create user name : user@xxxxxxxxxxxx and paswd xxxxxx? I was choise Basic authentication (password is sent in clear text) at Authentication Methods ? Does anyone has a clue about it? Thank You. My best regards Rizki
