Hello everyone! We recently went with a new provider for our live IP addresses and had to reconfigure our firewall with the new settings. We also updated our DNS records for all the new IPs. I don't believe anything else has changed but the problem we are having is with Outlook Web Access. We use to be able to access it via http://owa.domain.com&nbsp;when we try that address it takes us to an under construction page but if we use http://owa.domain.com/exchange&nbsp;we get prompted for our credentials. After the change our iphones stopped working. I'm not sure if this exchange issue would cause this or if it would instead be a DNS replication issue?? Like maybe the DNS records didn't propagate to all the real world DNS servers yet. I know this process takes some time. This happened yesterday so we are going to try today to see if the iphones are working with the same settings. Any help and info is greatly appreciated! Thanks

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
