A same message arrives at two different Exchange accounts, in an account the body of the message has information and in the other account the body of the message this emptiness. so that he appears empty?

The usual cause is AV or antispam software, or a firewall doing SMTP scanning that breaks the message so that it cannot be read by Outlook correctly. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources
