        When running without the ShowOriginalProgress parameter, the log files will be the standard output and the error output from the underlying tool executed
         
    .PARAMETER ShowOriginalProgress
        Instruct the cmdlet to show the standard output in the console
         
        Default is $false which will silence the standard output
         
    .PARAMETER OutputCommandOnly
        Instruct the cmdlet to only output the command that you would have to execute by hand
         
        Will include full path to the executable and the needed parameters based on your selection
         
    .EXAMPLE
        PS C:\> Enable-D365MaintenanceMode
         
        This will execute the Microsoft.Dynamics.AX.Deployment.Setup.exe with the default values that was pulled from the environment and put the environment into the operate / running state
         
    .EXAMPLE
        PS C:\> Enable-D365MaintenanceMode -ShowOriginalProgress
         
        This will execute the Microsoft.Dynamics.AX.Deployment.Setup.exe with the default values that was pulled from the environment and put the environment into the operate / running state
        The output from stopping the services will be written to the console / host.
