settings' problems

Everytime I check the mail, it compare a message : failed because user doesn’t have a caledar account. But the e-mails were dowloaded. What I have to do? Then, other question: when the mails were donwloaded, they were cancelled on the server. I would like they remain on the server, how I have to setting ? I thank you very much, Feliciana
