I have several issues reported by SCOM12 for Exchange 2013, most of the for mbx.
There is also HubTransport health issue on CAS servers. As for Dataprotection, I understand, that it is beacause of cercullar loging disabled, and in best practice it should be disabled. About the others, I found nothing useful, only it`s a bug, or if you did not expereance problems, did not touch expretions. Could you help with any of this issues, or perhaps any useful link.
