Configure Zentyal 4.0 to be a stand-alone replacement Exchange server

I have a virtual server running Zentyal 4.0 instance. The server must be a stand-alone replacement of exchange server. So all functions and modules to achieve this must be enable, also security settings. We have our own domain name that is longer then 15 digits, what makes it hard to setup this domain as primairy domain, because the problems NETBIOS is given us (SAMBA or OPENCHANGE). Goal with this setup is that Outlook clients (2010 + 2013) will be able to connect to the Zentyal server: * via autodiscover (see link [login to view URL]). * and via outlook anywhere For the autodiscover part, All DNS records need to be setup in a manner that outlook client will have no problems with autodiscover DNS access from the domain is prohibited, but I will be able to modify all records. For the job there will be access to the server through web access and through SSH if needed. The Zentyal configuration part need to be done, and that part can be reach through the vnc panel of my vps provider. The job will be completed if I can replicate all steps with documentation provided by the freelancer. And that I can login with a outlook client to the account created on the Zentyal server with both methods, and that I can send and receive mails. Please only react if you have implemented zentyal as a replacement server for exchange server and have prove of doing that. Thank you.
