There is one user in our premises who logs in his email account using two different computers.Few days ago appeared in his "main" PC a message "The rules on this machine do not match the rules on your Exchange server".He selected client and all the mails except the unread have been gone.The same message appeared in the other PC ,there he selected "server" without any problem.The point is that even if he opens his account through owa he cannot see his old mails.I export a csv file from the one PC that he had access and i imported to the other.After few days the problem appeared again.I found the following article from Microsoft but didn't help me. Any suggestion in order to solve that problem? Thanks in advance,
