    We have exchange 2013 HA environment (2 CAS and 2 MBX).
    i would like to know if the command test-smtpconnectivity can be run from any server to any server?
    for example can i run the command from MBx1 and provide it with MBx2 as the identity parameter?
    Also can we run it from the CAS servers?
