Can't set proofing language

[Cajuf]

I like to have the display language of all Office applications set to English. However, I mostly write in Portuguese with them.

In both Outlook and Onenote I can't make the proofing tool work in Portuguese despite having that language installed.

I'm running Windows 11 Home Single Language. Is that the reason why it won't work in any other language?

Hi @Cajuf,

do you have a Portuguese language pack installed on your Windows system?
Portuguese language pack installed on your Windows system can help with proofing in Office applications.

Here are the steps to install a language pack on Windows:

1. Select Start > Settings > Time & language > Language & region.
2. Choose Portuguese from the Add a language list under Preferred languages, and then select Options.
3. Select Download from the Download language pack option.
4. After the language pack is installed, select Back.

Yes, Portuguese language pack is installed, and even if it is my first preferred language, proofing will work as if I were writing in English. Have also tried repairing Office.

Maybe it has to do with being in a Single Language version of Windows?
