Can Teams spell check more than 1 Language?

Hi @MCota, 

Thank you for posting on the Microsoft Q&A forum. 

I truly understand how important it is to have accurate spellchecking when collaborating across different languages, and I appreciate you bringing this to our attention. 

Let me walk you through how Teams currently handles spellcheck and what options are available to support your multilingual workflow: 

Microsoft Teams relie on the Windows operating system's language settings to determine which language to use for spellchecking. At this time, Teams supports one spellcheck language at a time, based on your preferred language settings in Windows. 

This means if your system is set to English, Teams will check spelling in English only - even if you're typing in Spanish within the same message. 

If you frequently switch between English and Spanish, here’s how you can adjust your settings: 

1/ Open Windows settings 

Go to Start > Settings > Time & Language > Language. 

2/ Try to add Spanish as a Language (if not already added) 

Click Add a language, search for Spanish, and install it. 

3/ Then switch input language while typing 

Use the keyboard shortcut Windows key + Spacebar to toggle between English and Spanish input languages. This will also switch the spellcheck language in Teams accordingly. 

4/ Optional: try to use Microsoft editor for enhanced spellcheck 

If you use Microsoft Edge or Word Online, the Microsoft Editor extension supports multilingual spellchecking.
