Create Mail Account - Operation not permitted
Yesterday, I created a new email account for my domain and emailed the login information to my new partner. I'm not sure what he did, but today there is no email account. When I go to his User Details, I was told "This user does not have a mail account." When I try to Create an email account for him, I get the error message "Operation not permitted". I have already deleted his user account and started over, but am getting the same response.
