How to Fix Excessively Fast Horizontal Scrolling in Word and Excel
Question details
The user is experiencing abnormally fast horizontal scrolling when using a mouse in Microsoft Word and Excel.

- Product
- Microsoft Word and Excel
- Device & OS
- not provided
- Scenario
- Navigating wide documents or spreadsheets using a mouse with horizontal scroll capabilities.
- Observed behavior
- Horizontal scrolling is excessively fast in Word and Excel, while vertical scrolling and scrolling in other applications function normally.
Before troubleshooting, try testing your mouse in other applications like a web browser to confirm if the fast scrolling is isolated strictly to Microsoft Office. It is also highly recommended to save your current documents and close unnecessary background programs.
Test in Safe Mode and Disable Faulty Add-ins
Starting Word or Excel in Safe Mode helps identify if a third-party add-in is causing the scrolling issue.
Often, recently installed third-party integrations or COM add-ins conflict with the native scrolling behavior in Office applications. Running the app in Safe Mode bypasses these add-ins.
Press the Windows key + R simultaneously on your keyboard to open the Run dialog box.
Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) into the text box and press Enter.
Try scrolling horizontally in a document or spreadsheet. If the scrolling speed is normal, an add-in is likely the culprit.
Go to File > Options > Add-ins. Select 'COM Add-ins' from the Manage drop-down menu at the bottom and click 'Go'. Uncheck recently installed add-ins and restart the application normally to test.

Run Office Quick Repair or Online Repair
Corrupted Office files might cause unusual mouse behavior. Using the built-in repair tool can fix these underlying issues.
Update Mouse Drivers
Outdated or incompatible mouse drivers can sometimes conflict with Office applications.

Frequently Asked Questions
Why is horizontal scrolling only fast in Word and Excel?
This usually happens due to conflicts with specific COM add-ins, corrupted Office application files, or a mismatch between your mouse driver and Microsoft Office's rendering engine. Other applications use different rendering methods, which is why they remain unaffected.
Will repairing Microsoft Office delete my documents?
No, running a Quick Repair or Online Repair from the Control Panel only replaces or fixes missing and corrupted application files. Your personal documents, spreadsheets, and data will remain safe and unaffected.
Can changing Windows mouse settings fix this?
Sometimes adjusting the 'Choose how many lines to scroll each time' setting in Windows Mouse Settings can help, but if the issue is strictly isolated to Microsoft Office, troubleshooting add-ins or repairing the Office installation is usually required.
What if neither Safe Mode nor Repair works?
If both methods fail, you may need to completely uninstall and reinstall Microsoft Office. Alternatively, check if a recent Windows or Office update introduced a known bug, or contact Microsoft Support for further assistance.
