    The error message you are encountering with OneNote indicates that there is an issue preventing it from functioning correctly. This can happen for several reasons, including:

    1. Corrupted Installation: The OneNote application or other Microsoft products may have a corrupted installation.
    2. Add-ins or Extensions: Sometimes, add-ins or extensions can interfere with the normal operation of the applications.
    3. User Profile Issues: There could be issues with your user profile that affect how applications run.
    4. Conflicting Software: Other software on your computer may conflict with OneNote or other Microsoft products.

    To resolve this issue, you can try the following steps:

    • Repair Office: Go to Control Panel > Programs > Programs and Features, select Microsoft Office, and choose the Repair option. This can fix issues with the installation.
    • Disable Add-ins: Start OneNote in safe mode (hold down the Ctrl key while starting the application) and see if it opens without errors. If it does, disable add-ins one by one to identify the culprit.
    • Create a New User Profile: If the problem persists, try creating a new user profile in Windows and see if the issue occurs there.
    • Update Office: Ensure that your Microsoft Office is up to date, as updates can fix bugs and improve performance.

    If the issue continues after trying these steps, consider reaching out to Microsoft Support for further assistance.

    Dear @Joshi, Ayush ,

    Thank you for posting your question in the Microsoft Q&A forum. 

    The error you mentioned usually indicates a corruption issue in OneNote, the Office installation, or the local user profile. The Repair Now button inside the pop‑up usually does not fix the issue, so please try the steps below: 

    1/ Repair Office from Windows Settings 

    Navigate to Settings on your Windows > Apps > Installed apps 

    Find Microsoft Office or Microsoft 365 Apps 

    Select Modify 

    Choose Online Repair > Repair 

    Reference: Repair an Office application - Microsoft Support 

    2/ Clear the OneNote Cache 

    Open Run (Win + R) 

    Enter: %localappdata%\Microsoft\OneNote\16.0  

    Delete the Cache folder 

    Restart OneNote 

    3/ Completely Reinstall Office Using SaRA 

    Download SaRA: https://aka.ms/SaRA-officeUninstall 

    Run it and choose Office > Uninstall 

    Restart your PC and reinstall Office 

    Note: This method cleans up corrupted registry or configuration files that cause OneNote to crash. 

    If all check has passed but the issue persists, kindly provide more information below to let us work further: 

    • Does the problem occur with all OneNote notebooks, or only with a specific notebook? 
    • A screenshot of your OneNote Office version:  
    • Go to OneNote > File > Account > Product Information 
    • Please blur or hide any personal or private information before sharing. 
    • Do other Office applications (such as Word, Excel, or PowerPoint) show similar issues? 
    • Does the error also appear when you create a brand‑new test notebook? 

    Note: Please understand that as a forum moderator, my primary goal is to provide helpful guidance and support through general troubleshooting steps. While I don’t have access to internal systems or test devices required to resolve backend/account issues, I truly appreciate your understanding of these limitations. I genuinely hope the information helps you in the right direction, and we are always here to assist as much as I can within our scope.   

    I hope this information is helpful. Please follow these steps and let me know if it works for you. If anything is unclear, please don’t hesitate to reach out to me. 

    Thank you for choosing Microsoft, and I am looking forward to your response.
