Change state to inactive by Set-ServerComponentState doing nothing

I'm trying to put Exchange client components into inactive state

Set-ServerComponentState -Identity exch1 -Component ServerWideOffline -State inactive -Requester Maintenance

or

Set-ServerComponentState -Identity exch1 -Component OwaProxy -State inactive -Requester Maintenance

After that I'm still able to use OWA. Is it properly working?
