I have an AD domain contoso.local.
We don't host our external domain name in AD DNS , fabrikam.com
Now we want to setup OWA2013 (farm in nlb) with SP2013.
When creating the OWA farm we can give an internal and a external url.
For external url we want was.fabrikam.com but what would be ideal for internal url since we don't host the fabrikam.com zone internal in AD DNS.
For internal url was.contoso.local is also no viable option because a .local extension cannot be on a public cert.
My question was is the ideal solution in this case?
