When you deploy BitLocker management policies in Configuration Manager, clients automatically upload recovery keys and packages to the Configuration Manager recovery service
If a group policy setting exists for standalone MBAM, it will override the equivalent setting attempted by Configuration Manager. Standalone MBAM uses domain group policy, while Configuration Manager sets local policies for BitLocker management. Domain policies will override the local Configuration Manager BitLocker management policies. If the standalone MBAM domain group policy doesn't match the Configuration Manager policy, Configuration Manager BitLocker management will fail. For example, if a domain group policy sets the standalone MBAM server for key recovery services, Configuration Manager BitLocker management can't set the same setting for the management point. This behavior causes clients to not report their recovery keys to the Configuration Manager BitLocker management key recovery service on the management point.
