Intune

In configuring the Microsoft Intune Certificate Connector and attempting to issue certificates to your client via Intune you might run into the error message below.

IssuePfx – COMException: System.Runtime.InteropServices.COMException (0x80094800): The requested certificate template is not supported by this CA. (Exception from HRESULT: 0x80094800)at CERTENROLLLib.IX509CertificateRequestPkcs10V2.InitializeFromTemplateName (X509CertificateEnrollmentContext Context, String strTemplateName)
at Microsoft.Management.Services.NdesConnector.MicrosoftCA.GetCertificate (PfxRequestDataStorage pfxRequestData, String& certificate, String& password)

Failed to issue Pfx certificate for Device ID 24c2445e-6cd2-4629-a942-081bdaca9b12 :

In short when configuring the certificate name to be used you’ve probably entered the ‘Template display name’ instead of the ‘Template name’ – note the difference in the screenshot where the template name doesn’t include any spaces.

Given the complexity of this feature I’ve found the guide at this link really handy in setting it up in the past:
