Setup is 2012r2 domain controller with Essentials role for remote access. Exchange 2012sp3 installed on 2012. The Essentials server has connected to the Exchange server enough to create new user emails, but can't/won't forward OWA.
Server.domain.local/owa works internally. Remote.OutsideDomain.org/owa gives a 404 error from the Essentials server from inside or outside of the domain.
Anywhere access works, and has the link for email, which fails with the 404 error from the essentials server.
