I use EAS (ActiveSync) with Certificate authentication. I have been able to configure this without problems on iOS and Android. However, I don't know how to configure Certificate authentication for Outlook on Windows. I have already imported the PFX file into the Windows Certificate Store. Internet Explorer is able to Access the Active-Sync directory but Outlook is still not able to connect. Any ideas?
How do you obtain the certificate? You can check the using method with provider. Certificate for ActiveSync may be installed in AD: Certificate Authentication for ActiveSync
