I really need some help here. I had a requirement to change the green interface IP address and network subnet from 192.168.1.x to 192.168.50.x. I made the subnet change successfully, modified the IP addresses of the DC and OWA edge server accordingly, and changed the DHCP scope. Then I changed all the firewall port forwarding rules from 1.x to 50.x wherever they were present. Now, the exchange server is not receiving any emails and OWA does not work. What am I missing? Please help me!
