Note: The information in this article pertains to both Copilot for Microsoft 365 and Microsoft Copilot Pro.

If you're using Microsoft Copilot and you're getting an error that indicates a language isn't currently supported, it means that Copilot cannot process information in that language at this time. You can get an unsupported-language message even if the user interface (UI) is translated into your language.

This article describes what to do if you run into an unsupported-language issue and lists the languages that are currently supported.

What causes an unsupported-language error?

Microsoft 365 apps are localized into the user's language, based on the user's app settings. Here are some examples of how users can set their preferred language for various apps:

  • In Microsoft Teams, go to Settings > Language and choose the language you want to use for the Teams UI.

  • In Word, PowerPoint, or Excel, go to your account, choose Settings, and then select Change your language.

  • At, go to Settings > Language and time zone > Change your language.

  • At > Chat, go to Settings > Language, and then choose a display language and a search results language. The display language is the UI language, and the search results language is what Copilot uses for responses.

Currently, Copilot supports fewer languages than what's available for the UI. So although you can choose from lots of languages for the UI in Teams, Microsoft 365 Apps, and Bing, Copilot works with a fewer number of languages.

If you type a prompt in Copilot, and the language you're using or requesting isn't currently supported, you'll get an error message.

What do I do if I get a language error in Copilot?

Copilot provides responses to prompts that are written in supported languages. 

If you type a prompt that requests content in another language that isn't currently supported, Copilot displays a message telling you to change your prompt and try again. If you run into this issue, use one of the supported languages for your prompt and try again. 

What languages are currently supported in Copilot prompts and responses?

In general, Copilot supports the following languages for prompts:

  • Chinese (Simplified)

  • English

  • French 

  • German

  • Italian

  • Japanese

  • Portuguese (Brazil)

  • Spanish

Important: Currently, if you're using Excel in Copilot Pro, only English is supported.

Will more languages be added to Copilot?

Microsoft is planning to add more languages to Copilot. This article will be updated as additional languages are supported.
