Exchange On prem 1 parent 3 child domains
Hello all I have question and I hope I can articulate this as clear as possible. Our set up consist of 4 domains. One is the parent and the other are child domains. Exchange servers are built in each of the child domains, 1 per child domain and none in parent domain. Everything works however security is asking about why does an outlook client that is on child domain 1 trying to connect to the exchange server of child domain 2 and sometimes child domain 3?(almost like a round robin effect) I would like to explain to them in confidence rather just saying... that's just the behavior of the forest.. Even if it is just would like to explain it better. When I log into the EAC of child domain 1 i see servers for child domain 2, and 3 and if I change any settings it changes them across the servers. We are in closed environment but they want the environments isolated. I looked online but I have not found anything in regards to this type of set up.

- Generally Outlook clients on domain joined and connected workstations use the SCP record of the domain they are joined for autodiscover. The autodiscover process then provides the URLs that the Outlook client uses to connect to Exchange. You'll need figure out what the SCP URI is and also what URLs are being retuned by autodiscover and that will help establish why
