How to Fix Microsoft Copilot Unsupported Language Message
Question details
Users are receiving an unsupported language error when trying to use Microsoft Copilot, even though their Microsoft 365 interface is set to that same language.
- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Attempting to generate text, voice prompts, or interact with Copilot using a specific regional language.
- Observed behavior
- Copilot displays a message stating that the user's language is not currently supported for processing prompts.
Verify your current input language in Microsoft 365 and check Microsoft's official documentation to confirm if your language is currently supported by the Copilot AI engine.
Switch to a Supported Prompting Language
Change your input language to one that Microsoft Copilot currently supports for processing AI prompts.
The unsupported-language message appears because Copilot cannot currently process prompts in your selected language. The Microsoft 365 user interface may support a language for menus and settings even when the underlying Copilot AI does not yet support natural language processing in it.
Review Microsoft's official Copilot language documentation to see the current list of fully supported languages. For example, Copilot Voice currently supports English, Spanish, and Portuguese.
Translate or write your prompt in a supported language (such as English) before pasting it into the Copilot chat box.
If you want the entire experience to match, open your Microsoft 365 app, go to File > Options > Language, and set your 'Office display language' and 'Office authoring languages and proofing' to English or another supported language. Restart the application.

Frequently Asked Questions
Why is my language supported in the Microsoft 365 UI but not in Copilot?
Microsoft 365 menus and interfaces have been translated into dozens of languages over many years. However, Copilot relies on complex AI language models that require extensive training. These AI models are currently optimized for a smaller subset of languages.
Which languages does Copilot Voice currently support?
Currently, Microsoft Copilot Voice primarily supports English, Spanish, and Portuguese. Using other languages for voice prompts will trigger the unsupported language error.
When will Microsoft Copilot support my native language?
Microsoft is actively expanding the AI language models. New languages are continuously being trained and will be added gradually through standard Microsoft 365 feature updates.
