Overview of deploying languages in Office 365 ProPlus
Resources for Click-to-Run for Office 365 products are packaged similarly to the way standard Office 2016 Windows Installer (MSI) resources are organized. Language-neutral product resources are packaged into a single file that contains all the neutral resources. Language-specific resources are packaged into language-specific files such as en-us for English (United States) resources.
If you purchased an Office 365 subscription, you can use it to install Office in multiple languages. You do not have to buy a Language Pack. If your organization allows it, users can install Office 365 ProPlus languages directly from the Office 365 portal. When users install Office from the software page, they select a language from the Language drop-down box.
In managed enterprise environments, end-users may not have permission to install software from the Office 365 portal. If you are configuring an on-premises deployment of Office 365 Click-to-Run applications for users in your organization, you can use the Office Deployment Tool to install Click-to-Run in multiple languages.
The language elements that you specify in the configuration file for the Office Deployment Tool determine which languages will be installed. Administrators must specify the languages they want to install. The first language determines the Shell UI language. The Shell UI is the language that is used to display shortcuts, right-click context menus, and tooltips.
If you decide that you want to change the Shell UI language after an initial installation, you have to uninstall Click-to-Run and reinstall it. Add the language that you want to set for the Shell UI as the first language in the custom Configuration.xml file.
Additional language tools that you can install for Click-to-Run products include the following:
Language Interface Packs: Translated User Interface that installs over a copy of a Click-to-Run installation. You can download and install a Language Interface Pack for free. After you install it, you can use Microsoft Excel, OneNote, Microsoft Outlook, PowerPoint, and Word features in a different language. You can use the Office Language Preferences dialog after installation to change a language and see a translated user interface. For information about how to change the editing, display or Help language for Office applications, see Enable the use of other languages in your Office programs. To set Office 2016 language options on a computer that is running Windows 10, type "Office 2016" at the Start screen, and select Office 2016 Language Preferences to open the Microsoft Office 2016 Language Preferences dialog box.
Proofing Tools: Localized language versions of Office include proofing tools for a set of companion langauges. For more details and links to proofing tool downloads for each language, see Proofing Tools for Office 365 ProPlus.
ScreenTip Language: Translations that show the text of display elements such as buttons, menus, and dialog boxes in another language. You can download Microsoft Office ScreenTip Language 2013 from the Microsoft Download Center. ScreenTip Language installs over a Click-to-Run installation.
