How to Change Spell-Check Language in Microsoft Loop on Mac
Question details
Users want to know how to change or add multiple spell-check languages in Microsoft Loop on a Mac.

- Product
- Microsoft Loop
- Device & OS
- macOS
- Scenario
- A user needs to write notes and collaborate in multiple languages (such as English, French, Danish, or Italian) within Microsoft Loop workspaces on a Mac.
- Observed behavior
- Microsoft Loop lacks a built-in setting to add multiple spell-check languages or assign them per component. The spell check language is strictly tied to the user's Microsoft 365 account or tenant default, resulting in false spelling errors when typing in secondary languages.
Confirm the default language settings of your Microsoft 365 account and tenant, as Microsoft Loop heavily relies on these administrative defaults for its spell-checker rather than your local Mac system preferences.
Review Microsoft 365 Tenant and Account Settings
Since Microsoft Loop's spell checker is bound to your account's primary language profile, verifying your tenant settings can help explain why a specific language is being forced.
Currently, Microsoft Loop does not offer a dedicated menu to switch spelling languages on the fly. Behavior often defaults to the language associated with your Microsoft 365 tenant. If you use multiple accounts (e.g., personal vs. work), the spelling language will change based on which tenant that account resides in.
Open your web browser and navigate to your Microsoft 365 account profile or portal.
Click on your profile picture in the top right corner, select 'View account', and then navigate to 'Settings & Privacy' or 'Language and region'.
Check your preferred display language. If you have administrative access, verify the default language of your Microsoft 365 tenant, as this dictates the default dictionary in Microsoft Loop.
If you are experiencing the issue because you are in a tenant with a foreign default language, switch to a Microsoft account associated with a tenant matching your primary typing language.

Submit Feedback for Multilingual Support in Loop
Because the inability to assign multiple spell-check languages is a known structural limitation in Microsoft Loop, submitting direct feedback is the best way to request this feature.
Adjust macOS Built-In Text Input Settings
While Loop restricts in-app controls, ensuring your Mac's global spelling settings are configured for multilingual typing can sometimes assist browser-based text fields.
Enjoy Seamless Multilingual Typing with WPS Office
If the spell-check language limitations in Microsoft Loop are disrupting your multilingual workflow, consider switching to WPS Office. It offers comprehensive multi-language spell check capabilities, allowing you to change dictionary languages on the fly without being restricted by tenant settings.
- 1. Download and install WPS Office: Visit the official WPS website, download the macOS installer, and follow the on-screen instructions to set it up.
- 2. Open your document: Launch WPS Writer and start a new document or open your existing Microsoft Word files.
- 3. Set your Spell Check Language: Navigate to the 'Review' tab at the top, click on 'Spell Check', and select 'Set Language' to pick the exact dictionary you need for your current text.

Frequently Asked Questions
Can I assign a specific spell-check language to a single Microsoft Loop component?
No. Currently, Microsoft Loop does not support assigning distinct spell-check languages to individual components or workspaces. The spelling behavior is determined globally by your account or tenant language settings.
Why does my Loop spell check show a foreign language when my Mac is set to English?
This happens when your Microsoft account is part of a Microsoft 365 tenant where the default language is set differently from your local Mac. Loop prioritizes the tenant's language over your macOS system preferences.
Is there a way to disable the red spell-check underlines in Microsoft Loop?
Because Loop relies heavily on browser or tenant-level spell check APIs, you cannot universally disable red underlines natively within Loop's component settings. You may need to disable spell checking at the browser level, though this affects all websites.
Will Microsoft add multilingual spell checking to Loop in the future?
Many users have requested the ability to change spell-check languages per workspace. You can encourage Microsoft to prioritize this feature by submitting a request through the 'Give Feedback' button inside the Microsoft Loop application.
