Remove Exchange 2013 CAS roles when server is already gone?

Is there a way to remove CAS roles and anything else when the server is already gone?
I have three servers EX1, EX2 and EX3.  How can I remove EX2?
Here is  what I receive with one PowerShell command.
[PS] C:\Windows\system32>Get-AutoDiscoverVirtualDirectory

Name                                    Server                                  InternalUrl
----                                    ------                                  -----------
Autodiscover (Default Web Site)         EX1
The task wasn't able to connect to IIS on the server 'EX2.example.local'. Make sure that the server exists and
can be reached from this computer: The RPC server is unavailable.

I only want to remove EX2, not all of Exchange.  If I can leave it in the config, then I am happy to do so.

You can remove the Server from ADSIEDIT but just remember this can cause some other issues even later on so best practice would be recover the Server

Recover an Exchange Server
https://technet.microsoft.com/en-us/library/dd876880(v=exchg.141).aspx

And follow

https://blogs.technet.microsoft.com/mspfe/2015/08/26/decommissioning-legacy-exchange-servers/


In case you don't want to recover the Server and want to remove it from ADSIEDIT then you can follow the steps shared by Adam or below article
