I did use the website business plan with email on that plan and now Feb 1 all my plans changed to pro and email was separated to my hosting. Ok, I see how that makes it easier to manage email details but none of my users can login now. Does anyone else have this problem? I have a ticket in but was given no guidance on what I need to do, other than wait.
Ok, currently the system has changed from username@yourcompany.com to just using your username when logging into 'Mailbox User' address: http://#####.webmail.dynadot.com/user/signin.html. I'll try to update this as I learn more.
