Documentation
Policy DocsCCADBNotes about the documentation, such as which language the documents are in, or additional documents that need to be listed, as configured by the CA Owner.
Documents are in English. Microsoft's CP applies to both their external (publicly trusted) CA operations as well as their internal (not publicly trusted) CA operations. The Microsoft PKI Services CPS (Microsoft_PKI_Services_CPS) is for the external (publicly trusted) CA operations, so is the one governing this root certificate. The Microsoft PKI Services Corporate CPS (Microsoft_PKI_Services_Corporate-CPS) governs the private PKI of Microsoft PKI Services, so not relevant to this root certificate.
Doc RepositoryCCADBThe URL to the document repository pertaining to this certificate, as configured by the CA Owner.
Problem ReportingCCADBCCADB-published contact mechanisms for certificate problem reports and CA incident reports.
