Language packs add additional display, help, and proofing tools to Microsoft 365. You can install additional language accessory packs after installing Microsoft 365. If a language accessory pack is described as having partial localization, some parts of Microsoft 365 may still display in the language of your copy of Microsoft 365.

If a language is listed only once, German for example, then that pack includes the tools for all countries/regions that use that language.

Important: If your organization installed Microsoft 365 on your computer, contact your IT department to install any language packs.

Step 1: Install the language accessory pack

Select the version of Microsoft 365 you're using from the tabs below, then select the language desired from the drop-down list. Then choose the appropriate architecture (32-bit or 64-bit) from the download links provided. If you're not sure what you're using, see What version am I using?

Once the file is downloaded, open it to start installation. 

Step 2: Configure Microsoft 365 language

After you install the language accessory pack, you must configure Microsoft 365 for your new language preferences. This configuration affects all your Microsoft 365 applications.
