This issue isn't related with Autodiscover, in a coexist lab, you just need to one autodiscover record. About the connection issue, it is related with the virtual directories configuration on your Exchange server. About the certificate issue, it is related with the service URL and the subject that contained in your certificate.

Could you provided detail information about the certificate error? It will help us to narrow down this issue.

I also suggest you provide those information below to us:

 Get-OutlookAnywhere | Select Server,InternalHostName,ExternalHostName
    
 Get-MAPIVirtualDirectory | Select Server,InternalURL,ExternalURL 
    
 Get-OABVirtualDirectory | Select Server,InternalURL,ExternalURL
    
 Get-WebServicesVirtualDirectory | Select Server,InternalURL,ExternalURL
    
 Get-ClientAccessServer | Select Name,AutoDiscoverServiceInternalUri
    
 Get-OWAVirtualDirectory | Select Server,InternalURL,ExternalURL
    
 Get-ECPVirtualDirectory | Select Server,InternalURL,ExternalURL
    
 Get-ActiveSyncVirtualDirectory | Select Server,InternalURL,ExternalURL
    
 Get-PowerShellVirtualDirectory | Select Server,InternalURL,ExternalURL 
    
 Get-ExchangeCertificate | fl Subject,CertificateDomains,Services

I would also suggest you create a new mailbox on this new Exchange server, then check the look up step from Outlook "Test Email Autoconfiguration", those information will help us to know the detailed information in your organization and help you to narrow down it.

In a coexist environment, Autodiscover could redirect from one Exchange to another, you don't need to configure Autodiscover. And, one DNS record can only point to one IP address, it cannot bind with two DNS record.
