How to Fix OneNote Immersive Reader Grayed Out in Windows 10
Question details
The user is unable to use the Immersive Reader command in OneNote because the option is grayed out after installing the Learning Tools add-in.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10
- Scenario
- Attempting to launch the Immersive Reader via the Home tab in both personal and work notebooks using Microsoft 365 apps.
- Observed behavior
- The Immersive Reader command is visible on the Home tab but remains disabled (grayed out) and cannot be clicked.
Ensure you have an active internet connection and have actually clicked inside a text box with typed content, as Immersive Reader requires text focus to become clickable.
Verify OneNote Version and Select Text
Ensure you are using a compatible desktop version of OneNote and that text is actively selected before attempting to launch the tool.
The Learning Tools add-in is specifically designed for the older OneNote desktop client (OneNote 2016). If you are using 'OneNote for Windows 10', the Immersive Reader is already built into the View tab, and the add-in on the Home tab will not function correctly.
Additionally, the button will remain disabled until the application detects readable text on your current page.
Check your Windows Start menu to confirm whether you launched 'OneNote' (the desktop client) or 'OneNote for Windows 10'. The add-in only works on the traditional desktop client.
Click directly inside a text container on your standard notebook page or highlight a specific paragraph of text.
With the text selected, navigate to the Home tab and check if the Immersive Reader button has turned colored and is now clickable.

Update Microsoft Office and Learning Tools
Outdated Microsoft 365 applications can cause add-ins like Learning Tools to malfunction or display as grayed out.
Try WPS Office for a Hassle-Free Document Reading Experience
If Microsoft Office add-ins are causing persistent compatibility issues, consider switching to WPS Office. It provides a highly compatible, lightweight alternative with excellent built-in reading features—without requiring you to install and configure complex third-party add-ins.
- 1. Download the installer: Visit the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the downloaded setup file and follow the quick on-screen instructions.
- 3. Open your documents: Launch WPS Office and easily open your existing Office files to enjoy seamless reading and editing.

Does Immersive Reader require an active internet connection?
While basic text formatting features may work offline, many core Immersive Reader functions—such as Read Aloud voices, Syllables, and Translation—require an active internet connection to access cloud services.
