We are in the process of moving to hosted. Exchange. The autodiscovery record has been setup on the external DNS and when we are outside of the domain we can setup/connect and connect with outlook no problem. Internally it always connects to the internal email system. The dns internally is domain.com. I've set a cname record autodiscover.domain.com->autodiscover.outlook.com but this does not seem to work. It authenticates me using the hosted exchange email address and password but then connects to the internal exchange and not the hosted exchange.
The internal domain should have been domain.local but this is inherited. How do I bypass the internal Exchange server and use hosted exchange?
