Hello Jamie,
Thank you for confirming that the horizontal scrollbar is enabled in both Word and Windows.
Since it is still missing, let's try a few additional steps to see if we can restore it.
- Refresh the Word window
Right-click the title bar at the top of Word and select Maximize. Then right-click the title bar again and select Restore. Check whether the horizontal scrollbar reappears.
Microsoft provides further guidance in this article:
Show scroll bars in Word or Excel
- Adjust the document zoom
Try increasing the zoom level slightly using the slider in the bottom-right corner of Word. Check whether the horizontal scrollbar becomes visible.
- Refresh the document layout
If the scrollbar is still missing, try this workaround:
Save your document.
Open the Insert tab and select Cover Page.
Choose any available design.
Press Ctrl + Z immediately to undo the insertion.
Check whether the scrollbar has returned.
- Check for Office updates
Open Word, select File, then Account, and choose Update Options followed by Update Now. Install any available updates and restart Word.
Jamie, does this happen with all Word documents or only with a particular document?
If the issue persists, please also share your Word version and build number. You can find this information by opening Word, selecting File, choosing Account, and then selecting About Word.
This information will help me narrow down the cause and determine the most appropriate next steps.
Kind regards,
