We have a simple AD that was created years ago and migrated throughout time to Windows 2003. It has a single domain controller and multiple member servers. We are running Exchange 2007. I wanted to implement Outlook anywhere and deploy OCS. My problem is that we do not own the domain name we are using internally bvn.com. I wanted to rename the domain to bvn.domainweown.com, but I have found that is not possible. My question is, what is the best solution to accomplish this goal?

You can configure Exchange server to receive emails for your public domain bvn.domainweown.com by adding an acceptedauthoritative domain and applying email address of bvn.domainweown.com to all recipients to get mails delivered...

Oh yes, that had been done from the beginning. I'm now wanting to deploy outlook anywhere and I am concerned that I will have certificate issues becaused we do not own the domain name that we use internally. Will That be an issue?

Hi, If you have public domain name as bvn.domainweown.com, then we configure the bvn.domainweown.com as a accept domain, so that email address will with @bvn.domainweown.com. Also since we have bvn.domainweown.com as a public domain name, we point it to the CAS server, thus the certificate common name should be the public domain name. We can find that the we use https://bvn.domainweown.com/rpc to verify the RPC configuration.
