    Hello @Vibilu Balan, @Dodo ,

    A known issue has been confirmed by Microsoft in the September 2026 Excel security update. According to the published advisory, paste operations may fail silently in Excel 2016, Excel 2019, Excel 2021, and Excel 2024, which matches the behavior you described where copy appears to succeed but paste does not complete. Microsoft is currently investigating the issue.

    As this is a known issue associated with the update, it appears to be related to the Windows/Office update interaction rather than a problem with your Office installation itself.

    At this time, the available workaround is to roll back to a Windows version prior to the update where the issue was introduced, if this is permitted within your environment, and monitor Microsoft's advisory for further updates and a permanent fix.

    For detailed instruction, please check: Go back to the previous version of Windows | Microsoft Support

    Alternatively, I recommend waiting for upcoming Microsoft updates, as Microsoft is actively investigating the issue and may provide a fix in a future update.

    I hope this information helps.

    Hello @Vibilu Balan,

    As you mentioned that you have already tried everything, may I confirm whether you have gone through all the troubleshooting steps provided in the AI response, including testing Excel in Safe Mode, disabling add-ins, clearing the clipboard, and checking for conflicts with other applications?

    I would also suggest performing an Office Repair if you have not already done so:

    • Close all office apps completely.   
    • Go to Control Panel > Program > Programs and Features   
    • Right click on the Microsoft Office you've installed > Change.   

    > Control Panel > Programs > Programs and Features V C Search e Uninstall or change a program tes To uninstall a program, select it from the list and then click Uninstall, Change, or Repair. ures on or Organize

    • Select Quick Repair first (fast and doesn’t require internet).   

    - X Microsoft How would you like to repair your Microsoft 365 and Office programs? Quick Repair Fixes most issues quickly without the need for an internet connection. Online Repair Fixes all issues, but takes a little longer and requires an internet connection throughout. You can select this option if you are still having problems after a Quick Repair. Repair Cancel

    • If the issue persists, run Online Repair (requires internet and takes longer).   

    If all of those steps have been completed and the issue still persists, and since the problem started immediately after the Windows update and is affecting multiple users, I would recommend testing a rollback to the previous Windows version on one affected device to determine whether the recent update is the root cause.

    For detailed instruction, please check: Go back to the previous version of Windows | Microsoft Support

    Please note that Office 2019 reached end of support on October 14, 2025. While the application may continue to work, Microsoft no longer provides bug fixes, security updates, or technical support for this version. As a result, compatibility issues that arise following newer Windows updates may not receive a dedicated product fix. I would recommend planning an upgrade to a supported Office version to ensure continued compatibility and support.

    I hope this information helps.

    Best Regards,

    Use this troubleshooting path in order for the affected Excel 2019 devices:

    1. Check whether Paste Options is disabled in Excel.
      • Open Excel.
      • Go to File > Options > Advanced.
      • Under Cut, copy and paste, make sure Show Paste Options button when content is pasted is selected.
    2. Test Excel in Safe Mode to check for an add-in conflict.
      • Close Excel.
      • Press and hold CTRL and start Excel, then confirm Safe Mode.
      • Try copy/paste again.
      • If paste works in Safe Mode, disable add-ins one at a time until the conflicting add-in is found, then leave it disabled or uninstall it.
    3. Close all web browsers and test again.
      • Browser processes can conflict with Paste Special behavior in Excel.
    4. Install the latest Office and Windows updates.
      • Recent updates can correct problems caused by outdated files and known Excel issues.
    5. If Excel still hangs or paste remains broken, perform an Office repair.
      • Use the Microsoft 365/Office repair process from Control Panel or the Office repair guidance.
    6. If the issue started immediately after the Windows update and affects multiple users at the same time, test whether the update is the trigger.
      • On one affected PC, review Settings > Windows Update > Update history.
      • If the problem clearly began after a specific update, test removing that update on the pilot machine first, restart, and verify whether paste works again.
      • This should be tested on one machine before wider rollback.
    7. If Excel becomes unresponsive rather than only failing to paste, continue with conflict checks:
      • Perform a selective startup (clean boot) to identify a background process or service that conflicts with Excel.
      • Check whether antivirus integration with Excel is causing the issue. Disabling antivirus integration can reduce conflicts, but this has security risk and should be done carefully.

    If all three users were updated on the same date and the issue appeared at the same time, the most likely paths are:

    • a conflicting add-in loaded in normal mode,
    • a Windows update side effect,
    • or another background process/security integration affecting Excel.
