How to Stop OneNote from Automatically Changing Acronyms like EHR
Question details
The user needs to prevent OneNote from automatically replacing the typed acronym EHR with HER.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10
- Scenario
- Typing specific acronyms in OneNote without having them automatically replaced by other words.
- Observed behavior
- When the spacebar is pressed, OneNote automatically changes the acronym EHR to HER. The word is not marked as a spelling error, and the user cannot locate the AutoCorrect setting in the web or Windows 10 application.
Ensure you have access to the classic desktop version of Microsoft OneNote included with the Microsoft Office suite, as the Web and Windows 10 apps do not contain the necessary AutoCorrect settings.
Modify AutoCorrect Options in the Desktop OneNote Application
Use the full desktop version of OneNote to locate and remove the specific AutoCorrect replacement entry that is changing your acronym.
This issue is caused by an AutoCorrect replacement rule, rather than a standard spelling-check error. Because OneNote for Windows 10 and OneNote for the web lack detailed AutoCorrect configuration settings, you must use the classic desktop version of OneNote to fix this behavior.
Launch the desktop OneNote application that is included with your Microsoft Office suite.
Click on the 'File' tab located in the top-left corner of the application, and select 'Options' from the menu.
In the OneNote Options window, click on 'Proofing' in the left sidebar, then click on the 'AutoCorrect Options...' button.
In the AutoCorrect tab, scroll through the list of replacement entries to find the rule that replaces 'EHR' with 'HER'. Select the entry and click 'Delete', then click 'OK' to save your changes.

Switch to WPS Office for a Streamlined Document Experience
If you are frustrated by missing settings in stripped-down web or default Windows apps, try WPS Office. It provides a full-featured, lightweight, and completely free alternative to Microsoft Office, giving you complete control over your text, AutoCorrect settings, and formatting.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install the Software: Run the installer and follow the straightforward on-screen instructions to set up WPS Office.
- 3. Open and Edit: Launch WPS Office to instantly open your existing Microsoft Office files and easily configure your preferred AutoCorrect settings.

Frequently Asked Questions
Why does OneNote change my acronyms even when the spelling check is disabled?
This happens because of the AutoCorrect feature, which functions independently of the spelling checker. AutoCorrect automatically replaces specific letter combinations with predefined words as soon as you press the spacebar.
Where is the Options menu in OneNote for Windows 10?
OneNote for Windows 10 has a simplified Settings pane accessible via the three dots (ellipsis) in the top right corner. However, it does not include the advanced 'File > Options' menu or the comprehensive AutoCorrect dictionary found in the classic desktop version.
How can I disable AutoCorrect in OneNote entirely?
In the desktop version of OneNote, go to File > Options > Proofing, click on AutoCorrect Options, and uncheck the box for 'Replace text as you type'. This will completely stop all automatic word replacements while you type.
