In this article we will assign services to a certificate in Exchange 2016. We explore how to accomplish this using Exchange Admin Center and PowerShell.
Let’s get started!
Assign Services to a Certificate with Exchange Admin Center
Log into the Exchange Admin Center (EAC). Select the Servers tab and Certificates sub tab.
Select your certificate and click the Edit () button.
Select the Services tab. Pick your desired services. Click Save. In our example we just picked IIS.
This may take a minute or so to process. Once complete you will see the certificate has been assigned to the services you picked. In our case IIS is now assigned to the certificate.
Assign Services to a Certificate with PowerShell
If you prefer to assign services using PowerShell you would use the Enable-ExchangeCertificate cmdlet. Using our example above our command would look like this:
C:\> Enable-ExchangeCertificate -Thumbprint <ID> -Services IIS
You can obtain the thumbprint by running Get-ExchangeCertificate.
In this command:
- -Thumbprint specifies the certificate to configure via its thumbprint.
- -Services define which components you want to use the certificate with (e.g. IIS, SMTP, etc.).
To verify the services have been assigned run the Get-ExchangeCertificate command.
C:\Users\supertekboy\Desktop>Get-ExchangeCertificate Thumbprint Services Subject ---------- -------- ------- 559642FCD3DD4769D79A457D11875AF9E6E49F3C ...WS.. CN=webmail.exchangeservergeek.com, OU=Exchange Server Geek, O=S...
The services column indicates what services are currently assigned to the certificate. In the example above IIS (W) and SMTP (S) have been assigned to this certificate.
Other possibilities include POP (P), IMAP (I) and Unified Messaging (U).
Checking your work
Now that we have our new certificate installed, we need to test to make sure it is working properly.
The easiest way to check is to enter your URL into a web browser. In our case we enter https://webmail.exchangeservergeek.com/ecp. This should result in no certificate errors.
Let’s test AutoDiscover as well. In our case https://autodiscover.exchangeservergeek.com/autodiscover/autodiscover.xml. You will be prompted for credentials. Once entered you will receive the following response. Despite it being an error it is expected behavior. Autodiscover was expecting Outlook, not Internet Explorer.
Tests results all good? Awesome! Your certificate is correctly installed.
More than one server?
If you have multiple Exchange servers it is important that we copy this certificate to each Exchange Server. To do this check our article on importing and exporting Exchange certificates.
