Hello,

We are trying to use the Kibana integration with Microsoft Exchange. We are being told that the requirement is to use certificate based authentication instead of the clientSecret string. Is there a supported way to authentication with a Microsoft app certificate instead of clientSecret?

Thank you,

Joe
