How to Fix Fast Horizontal Scrolling in Word and Excel

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.

Solution 1Recommended

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.

1
Open the Run Dialog

Press the Windows key + R simultaneously on your keyboard to open the Run dialog box.

2
Launch Office in Safe Mode

Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) into the text box and press Enter.

3
Test the Scrolling

Try scrolling horizontally in a document or spreadsheet. If the scrolling speed is normal, an add-in is likely the culprit.

4
Manage and Disable Add-ins

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.

Test in Safe Mode and Disable Faulty Add-ins
Add-in Identification: To pinpoint the exact add-in, re-enable them one by one, restarting Word or Excel each time, until the fast scrolling returns.

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.
