Exchange 2016 certificate issues
Posted on 2016-10-10
Before, we had an exchange server with 2 NICs: 1 internal LAN, 1 external WAN.
The LAN was linked to our active directory domain server. It used an internal IP and hostname (mydomain.corp)
We have changed our network. We now use 1 interface, WAN only. (yes, it is secured, hosted).
However, since then, we keep getting SSL certificate errors when starting outlook.
We have an external hostname: https://remote.myfqdn.com/ , which runs a Geotrust EV certificate.
I have that as IIS binding.
The complaint however is about the exchange.mydomain.corp interface. (private).
This is a local hostname, and is locally used (used inside the domain).
Before, I could bind it to 2 seperate interfaces: One to my 10.0.0.0/8 interface LAN, and the other to the WAN.
Now, that is not possible.
How can I stop this annoying error?

Most likely you just need to reconfigure your Active Directory Autodiscover SCP settings. http://wp.me/pUCB5-7X has more info.

Thanks for your response. I have already tried all of those, using powershell. Interesting article though. Same thing, but different approach.
