Missing language in spelling check on New Teams

I was able to fix this issue only on the Web app on the Ms Edge browser.

I mark those options:

Hello. I have the same issue with Finnish language. I type in Finnish and every word is underlined with squiggly red line. There is no option to change the proofreading language in the NEW teams.

I want to keep the Teams program itself in English but I want to be able to change the spell checking language to Finnish. Better yet if the spell checking language could be changed based on person, just like in the old Teams.

I have the same issue. The only option I found was to turn of spell check completely as I could not even see any typos anymore.

Let me know if you find a solution...

Hello MDERM,

I'm Segunfunmi, an Independent Advisor and Microsoft user like you. Thank you for posting your query in this forum.

I understand how important it is to check your spelling in your preferred language. So, to enable Polish spelling check in Microsoft Teams, you can try these easy steps:

1. Write a few messages in Polish in a chat or channel to automatically activate the language-aware spell checking. If needed, a message will pop up asking you to confirm the language you're using.
2. Switch between different keyboard layouts by using the Language bar. The default spell-check language in Teams is based on your Windows keyboard language. Simply click the language icon in the Language bar (near the clock on your Windows taskbar) and choose the language you want to use.
3. Use the keyboard shortcut Alt+Shift to switch between different keyboard layouts on Windows devices.

Please remember that language-aware spell-checking is only available for Teams desktop users on Windows. If you need further help, you might want to try clearing the Teams cache or restarting Teams.
