The connector can be configured to run under the SYSTEM account or optionally (and recommended) a domain service account. When using a service account, the service account must have permission to log on as a service on the server where the Intune Certificate Connector server.

Even when all prerequisites are met, administrators may still find the installation of the Intune Certificate Connector fails with the following error message.
