After installing Exchange Server 2016 CU9 in coexistence with Exchange Server 2010, we are getting the following errors constantly being logged:
Event ID 258 MSExchange RBAC: RemotePS Public API Func GetApplicationPrivateData throws Exception Microsoft.Exchange.Configuration.Authorization.CmdletAccessDeniedException: The operation couldn't be performed because '<Exchange server object>' couldn't be found
Event ID 23 MSExchange RBAC: Exchange AuthZPlugin Fails to finish method GetApplicationPrivateData due to application exception Microsoft.Exchange.Configuration.Authorization.CmdletAccessDeniedException: The operation couldn't be performed because '<Exchange server object>' couldn't be found.
Event ID 16 MSExchange RBAC: RBAC authorization returns Access Denied for user <Exchange server object (SID=S-1-5-21-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx). Reason: User was not found on Domain Controller <DC FQDN>"
I can't find any references to a solution to this issue anywhere, nor where I should start troubleshooting, so any help would be greatly appreciated.
