I have two laptops, on one I can get into the Elite Mail LX system but on the other I get a message that the account settings do not allow me to use the Web Mailbox Manager. Please contact your system administrator if you need more information. I'm the system admin and I know the user name and password work since it works on one laptop but not the other. I've compared all the obvious settings and there are no differences. Why can I login from one system but not the other?
