How to Change the Office Online Server Interface Language
Question details
The user wants to know how to change the global interface language for Office Online Server.
- Product
- Office Online Server
- Device & OS
- not provided
- Scenario
- Deploying or maintaining an Office Online Server environment where users need the interface displayed in a specific language, such as Portuguese.
- Observed behavior
- The global interface language is not controlled by a single server setting, but rather depends on a combination of user preferences, browser settings, and installed server resources.
Ensure you have administrator access to the server hosting Office Online Server and verify that the target language packs are available for download from the Microsoft Volume Licensing Service Center.
Install Language Packs and Configure Preferences
The officially supported method to display a specific interface language is to install the appropriate language pack on the server and ensure user clients are configured to request that language.
Office Online Server relies on the client's browser settings and account preferences to determine the display language. By installing the necessary language resources on the server, OOS can fulfill these localized requests.
Download the desired language pack (e.g., Portuguese) for Office Online Server from the Volume Licensing Service Center and run the installer on the server infrastructure.
Verify that user accounts in Active Directory or the connected SharePoint environment have their regional and language preferences set correctly.
Instruct users to navigate to their web browser's language settings and move the target language (e.g., Portuguese) to the top of the preferred languages list.
Implement IIS URL Rewriting as a Workaround
If you must force a specific language globally and cannot rely on client settings, an advanced administrator can configure URL Rewrite rules in IIS to append language parameters.
Experience Multi-Language Support with WPS Office
If configuring complex server language settings is too burdensome, consider WPS Office. It is a robust, lightweight, and completely free alternative that allows users to switch interface languages easily without requiring server-side configurations.
- 1. Download the installer: Visit the official WPS Office website and download the free version for your operating system.
- 2. Install the software: Run the setup file and follow the straightforward prompts to install WPS Office on your device.
- 3. Change the language easily: Open the application, click on the Global Settings icon, navigate to Language, and select your preferred language in seconds.
Frequently Asked Questions
Is there a single toggle in Office Online Server to change the global language?
No, Office Online Server does not have a native global setting to force a specific interface language. It relies on the installed server language packs combined with the individual user's browser language and Active Directory preferences.
Where can I download language packs for Office Online Server?
Language packs for Office Online Server are available exclusively through the Microsoft Volume Licensing Service Center (VLSC) for enterprise customers with active agreements.
Why is my Office Online Server interface still in English after installing a language pack?
Even if the language pack is installed, the server displays English if the user's web browser settings or SharePoint profile preferences prioritize English. You must configure the client browser to request the new language as its primary choice.
