In our production environment we have a AD domian called ABC.com and the internet registered domain is called XYZ.com. The internal domain ABC.com is also published on the internet but by another organization and we do not have control over it. Now we want to publish OWA, autodiscover and activesync on the internet with the domain we have published which is XYZ.com pointing it to the CAS array of ABC.com. Can we get a solution for this please. We have TMG, and internal CA in production environment.
