My user have his blackberry for a while now. Everything was working fine (send and receive, etc).
One day he was unable to send or reply email. We discover that the windows domain administrator right has been assigned to him. So we removed it. Resend Policies, Reboot servers and reload the user.
I don`t know what else to do. I am thinking of removing / delete the user from the BES or simply change Blackberry device.
