I cannot send e-mail from one account on a single computer. When we travel, my wife and I both use the same ASUS Transformer Prime, which is a pad computer, for our e-mails, which are both Verizon accounts. When she logs on, she can send and receive just fine. But when I log on I can receive, but when I try to send the "send" button grays out but nothing else happens. I don't have this problem when I log on with any other computer. Any thoughts?
