With Dynamics 365 Portals, global companies can take advantage of how easy it is to support multiple languages. Out of the box, nearly every major language is supported. By default, every language supported is installed with the portal application. However, portal administrators still need to install the desired language into the Dynamics 365 instance. Once the new language is installed, Dynamics 365 automatically adds additional records to support the new localized content. While you can select to install multiple languages at the same time, we had better performance results by installing them individually.
