Hi, I am in Cincinnati, Ohio and getting ready for a new school year. Our students arrive next Monday. In our faculty in service days I am trying to send documents over email, and I keep getting a message that I can't send or save the message. I have never had trouble sending documents before, and I have had this iPad for two years. I have checked for updates, I have tried multiple locations and networks, I have tried restarting.... Any other suggestions that might get this up and working again?
