I'm going to be moving away from local Exchange this year in favor of hosted. I have a general question about something I don't understand.
My domain.com has an external DNS, but also an internal AD DNS for everything on the inside (same domain name). Externally I have an auto discover record and all that and the Outlook anywhere clients work just fine. I would change to autodiscover record and Outlook clients would begin using the new host.
Now internally on the AD domain I do not have any autodiscover record and all the Outlook clients still automatically connect to my internal exchange server and configure themselves just fine. However, I don't understand how that actually works without an autodiscover record. I'm asking this because I don't know what would be needed to internally make the Outlook clients start connecting to the new external host. I know I would need to add an autodiscover record internally, but would that work and how is it even working now?
