Certificate Connector / Publish User Certificate in Active Directory

Hey guys,

I could need some help. I've installed and setup successfully the intune certificate connector. When I roll out the device (iOS) in Intune, the user certificate is successfully generated and installed on the device. But the certificate is not stored in the user account in Active Directory.

Since we want to switch our Exchange ActiveSync to certificate-based authentication, the issued certificates must be associated with the user account in AD.

I have also already issued enrollment agent certificate for the connector service account. Unfortunately, that did not help either.

Thanks for any help in advance.

Edit 1: The checkbox "Publish in Active Directory" ticked in the certificate template
