Certificate Problem? When you install Exchange Server 2016 into your Active Directory environment the setup process registers a Service Connection Point (SCP) for the Autodiscover service. Autodiscover is used by client applications to discover information about Exchange mailboxes and services. For example, Outlook uses Autodiscover during the setup of a new Outlook profile to discover the server settings for the user, so that the profile can be automatically configured (instead of the old days of manually entering server names and other details into Outlook). By default the Autodiscover SCP is registered using a URL that includes the Exchange server's fully-qualified domain name. You can see the Autodiscover URL for an Exchange 2016 server by running the Get-ClientAccessService cmdlet in the Exchange Management Shell. For example: [PS] C:\>Get-ClientAccessService -Identity EXSERVER | Select AutodiscoverServiceInternalUri AutoDiscoverServiceInternalUri ------------------------------ https://exserver.exchange2016demo.com/Autodiscover/Autodiscover.xml Note: Previous versions of Exchange used the Get-ClientAccessServer cmdlet.

I was expecting clients to get errors on the certificate as they are connected to the mail.mylocaldomain.local name. I have read a lot of documentation and they all pretty much say the same thing: add new zone on local DNS server with the public domain (I added a zone mydomain.com) add a record A pointing to the local ip of the email server (I added mail.mydomain.com pointing to local IP of the server) I have issued these commands: Set-ClientAccessServer -Identity EXCHANGE-MAIL -AutodiscoverServiceInternalUrihttps://mail.publicdomain.co.uk/autodiscover/autodiscover.xml Set-WebServicesVirtualDirectory -Identity “EXCHANGE-MAIL\EWS (Default Web Site)” –InternalUrlhttps://mail.publicdomain.co.uk/EWS/Exchange.asmx Set-OABVirtualDirectory -Identity “EXCHANGE-MAIL\OAB (Default Web Site)” -InternalURL https://mail.publicdomain.co.uk/OAB Set-ActiveSyncVirtualDirectory -Identity “EXCHANGE-MAIL\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURLhttps://mail.publicdomain.co.uk/Microsoft-Server-Activesync Set-WebServicesVirtualDirectory –Identity ‘EXCHANGE-MAIL\EWS (Default Web Site)’ –ExternalUrlhttps://mail.publicdomain.co.uk/ews/exchange.asmx with the proper names in them, but my clients are still getting the certificate error.

Internal Names - Part II Reconfigure your Microsoft Exchange Servers to use your registered domain names instead of internal names. Internal name and reserved IP address certificates will expire by October 31, 2015. If you are reading https://blog.digicert.com/replace-internal-names-certificates-part-2/ this blog because you are knee-deep in replacing your publicly trusted internal name certificates, you have come to the right place. If you are just learning about replacing your internal name certificates, see our http://stackoverflow.com/questions/29301202/exchange-server-wildcard-certificate-error previous post Replacing Your Internal Name Certificates.

This will not actually change your server name or AD domain. We recommend subscribing to this blog. We will keep it updated if additional information or changes are required.

You only need to run the Internal Name Tool or Exchange Management Shell (EMS) commands on one CAS server, and it will update the configuration for all of them.

We also have a wildcard certificate and wanted to use that certificate for Exchange. We got the certificate installed correctly, but we get an error notice when Outlook connects to Exchange. The error is: "exchange.office.domain.com ... The name on the security certificate is invalid or does not match the name of the site" When I "View Certificate...", I see the correct certificate, issued to "*.domain.com" I am not sure if the problem is that the * does not work for exchange.office, that is how we have the network setup however. Does anyone know how we can get Exchange to work with the wildcard certificate (we do not want to buy another certificate for testing), or if the problem is the multi-host in the FQDN, how we can get around that?
