Spell check in multiple languages
It would be nice if it was possible to have the Teams desktop app in one languge and spell checking in multiple languge and at the same time customize date and time format.
E.g. I would like to have Teams in English, have spell checking in English and Danish, and have date and time format in "Danish".

Thank you for your feedback! We are happy to share that users who write different messages in different languages, will now see spellchecking relevant to the language they are actively using when typing a message while using the Microsoft Teams Desktop App on Windows.

It should be possible to set a default language, but override it for each view. It's quite possible that one conversation might be in English and another in Spanish, for example.

I meant Win + Space of course.

Currently Teams uses the Teams UI language when spell checking. So that if I want to switch between typing in Swedish and English I have to restart Teams which isn't very convenient.
To better support multiple languages I think it should use the current Windows setting instead. So if I change input language in Windows using Ctrl + Space, Teams should recognize this when spell checking.
That would allow me to keep the Teams UI in English as I prefer and be able to get spell checking both when typing in English and Swedish.

Office has gone so far backward on international support for these basic elements!

It lacks the possibility to just disable spell checking. I don't need it at all, please add also a disable functionality.

No feedback on this? It seems an obvious omission given that most software supports multi-language spell checking.

This is a very important feature to have for non-english speakers, especially in an international company. On macOS the operating system provides built-in spell checking for text fields. This supports multiple languages and is not tied to the language used for the UI.

I'm using Teams in English (I prefer English UI in my software), but with my colleagues I'm mostly chatting in Hungarian. Thus in the desktop app I get all of my Hungarian messages underlined in red (it's OK if I also switch the UI to Hungarian). There is no such issue in the web app, I'd guess because it uses Chrome's adaptive spell checker.
Ideally I'd like to see the same kind of multi-language spell checker in the desktop app as well, but I can also live without spell checking, so even the ability to disable it would be fine for me. However having all my text underlined is really distracting.

+1 for adding multi language spell check support in the Microsoft Teams Windows 10 app. Using WinKey+space to switch language in Temas the same way as you can do in Skype and in the Edge browser, sounds like a reasonable request.

The language used for spell checking should be configurable globally, and per-channel (including chat)

I noticed this happens when you edit a letter within a word after the fact.
Steps to reproduce
type feedback
then change b to d
so you have feeddack
now right click and you'll see suggestions for either feedd or ack (depending on what part of the word you click) -

It would be good to have non-US spelling for system messages as well - e.g. favourite

Or just disable the spell checker by default

Currently in Teams Windows Client, only English spellchekers seems to work. We need other languages as well. Could use Office spellcheckers since they are already installed on most E3/E5 plans anyway

The choice of spell checker (including "none") should be available on a per-channel basis.
It's quite plausible to be having a conversation with one team in Spanish and with another in English, at the same time.

Any chance of disabling spell checker in #MicrosoftTeams? making it optional? Many of MS users speak multiple languages + it'd lead to leaner, faster, more visually friendly app.

Wish spell check could be optional. Also being able to switch language within text like in OneNote. Use Win-Key + space to change language. In OneNote (Windows - not Mac) even single words can be spell checked in different language.

Even when set to English UK, the dictionary is English US ... a classic is to spell the word colour ... Outlook flags it as incorrect, when it is perfectly fine, and there is no way to change it. Other software allows you to right click on a misspelled word, and have access to the different spell check languages. Not Outlook. There is no way to use an English dictionary, we're stuck with US English. For any company, misspelling words is not professional and this affects the companies image. On top of which, I, for example, am dyslexic. Without a functioning dictionary which I can trust... I've got real problems.
