Disabled export layer to CSV file

Question

Hi, I have a feature service published in an arcgis server A, and registered in Portal on Machine B. (Non hosted service)
I connecte excel's arcgis for office Producto to portal, and successfully added the feature service to an excel map.

However I found no way to export the layer data as a CSV. (because the option appears grayed)
I also tried with hosted service and the option looks still disabled

I would apreciate any ideas. 
Regards

Thanks for your response

the problem is that this option only appears for hosted services , and we need to work with non-hosted

Shooting in the dark here as I don't have Portal installed and Maps for Office doesn't work with our Office 365.

From everything I've heard it's basically ArcGIS Online for your own network though.  With a feature service, in AGOL, there is a checkbox at the bottom of the page under the Settings tab to allow others to export different formats.  By default it is unchecked.  Could it be that simple?
