    Hi Jeet Chaturvedi,

    I understand how frustrating it can be when both OneNote and Excel repeatedly ask for a repair, especially when you cannot use the applications normally.

    Since both applications are affected, the Online Repair suggested above is a reasonable first step because repairing Microsoft 365 applies to the entire Office suite, not just one application.

    After the repair is completed and the computer has restarted, please check for Office updates by opening any Office application that still works and going to File > Account > Update Options > Update Now. You can refer to Microsoft’s official guidance here: Update Microsoft 365 or Office for Windows.

    If the repair prompt continues to appear, please share the exact wording or a screenshot of the prompt and confirm whether Online Repair completes successfully or shows an error. It would also help to know whether any other Office applications are affected. This information can help to narrow down whether the issue is with the overall Office installation or specific applications. Thank you so much for your understanding.

    Run an Online Repair of Microsoft 365 because both OneNote and Excel are affected; repairing Microsoft 365 repairs the entire Office suite, not only one application.^1^

    Repair Microsoft 365

    1. Close OneNote, Excel, and all other Office applications.
    2. Open the repair settings:
      • Windows 11: Right-click Start → Installed apps.
      • Windows 10: Right-click Start → Apps and Features.
    3. Find Microsoft 365 or your named Microsoft Office product.
    4. Select the three dots if displayed, and then select Modify.
    5. If prompted for permission, select Yes.
    6. Choose:
      • Click-to-Run installation: Online Repair → Repair. Use Online Repair rather than Quick Repair because it performs the more complete repair.
      • MSI installation: Repair → Continue.
    7. Complete the prompts and restart the computer.
    8. Open Excel and OneNote to test them.

    If Online Repair does not fix both applications

    Completely uninstall and reinstall Microsoft 365. Uninstalling Office removes the applications but does not remove documents or workbooks created with them.^2^

    1. Press the Windows key, type Control Panel, and open it.
    2. Select Programs → Programs and Features.
    3. Select Microsoft 365 or your Office suite, and choose Uninstall.
    4. Follow the prompts and restart Windows.
    5. Sign in to the Microsoft 365 Apps page using the Microsoft account—or work or school account—associated with the product.
    6. Select Install apps → Install or Microsoft 365 apps.
    7. Run the downloaded installer and wait for “You’re all set! Office is installed now.”
    8. Open an Office application and complete activation if requested.^3^

    If Microsoft 365 is not listed in Control Panel, it may be a Microsoft Store installation; use the Microsoft Store uninstall instructions on the referenced uninstall page instead.^2^
