Can I add section breaks in Word Online?

Unfortunately, no. You can add page breaks but Word Online can't add section breaks yet.

To insert a page break, click Insert > Page Break.

If you have the Word desktop application, use the Open in Word command to open the document and add section breaks there. When you're done and you save the document, it will continue to be stored where you opened it in Word Online.

If you don't have Word, you can try or buy it in the latest version of Office now.

Tip: Office Online is updated all the time with new features. Subscribe to the Office Online blog for the latest news and announcements.
