I have a user that is using a Cingular Edge Card for internet connection. He can send and receive Email fine. However, when he is connected to the edge card and tries to open an attachment (small or large), Outlook 2003 goes to not responding. While Outlook 2003 is doing this, if he disconnects from the Edge card the attachment opens correctly. I am confused on what might be causing this since other users of Edge cards in the office are having no issues. The Email accounts are POP3.
