Server 2012 R2
Exchange 2013 SP1
My router failed and I had to replace it as well as cable modem (fried). That caused Comcast to issue me a new external IP address. I reconfigured the port forwarding to the correct version and changed my Godaddy pointers for mail.mydomain.com. AutoDiscover points correctly. I can ping mail & autodiscover and the external IP address is correct.
Problem:
1. When I open EAC on exchange server, I get a certificate error upon open. I can logon. The certificate name is the correct one, mail.mydomain.com
2. Outlook client cannot connect. I tried repair and get error: problem with proxy server security certificate. The name on the security certificate is invalid or does not match the name of the target mail.mydomain.com Error code 10.
I made no changes to the configuration nor certificate before the router & cable modem failure. How do I get this corrected?
Thanks
