    .SYNOPSIS
    Bring Exchange components to active state.
    .DESCRIPTION
    Bring Exchange components to active state.
    .PARAMETER HybridServer
    Indicates to check 2 additional Server Components that are important for
    Office 365 synchronization between the On-premises environment and the
    Exchange Online environment : "ForwardSyncDaemon" and "ProvisioningRps".
    .PARAMETER CheckOnly
    Indicated the script to only check which Components are inactive before
    attempting anything.
    .EXAMPLE
    .\Start-E2016ServerComponentStateToActive.ps1 -HybridServer -CheckOnly
    Will check all Server Components, including ForwardSyncDaemon and ProvisioningRps
    components, but won't attempt to start these.
    .EXAMPLE
    .\Start-E2016ServerComponentStateToActive.ps1
    Will check all Server Components, excluding the ForwardSyncDaemon and ProvisioningRps,
    and attempt to start these.
    The script will tell you if the operation was successful or not.
    .EXAMPLE
    .\Start-E2016ServerComponentStateToActive.ps1 -HybridServer
    Will check and try to start all Server Components, including ForwardSyncDaemon and ProvisioningRps
    .EXAMPLE
    .\Start-E2016ServerComponentStateToActive.ps1 -CheckOnly
    Will check all Server Components, excluding ForwardSyncDaemon and ProvisioningRps
    components, but won't attept to start these.
