As an admin, you can control whether or not you want to let people in your organization use external services, such as Bing Translator, to translate documents on your site.
This setting is turned on by default. If you have a business need to make your site compliant with a specific set of standards, you may not want to have site users accessing external services. In this case, you can turn off access to external services.
For more information about compliance-related issues, see the Office 365 Trust Center website.
