Question details

Users need to resolve an issue where SharePoint email banners no longer span the full width of the page, leaving gaps on the sides in previews and delivered messages.

How to Fix SharePoint Email Banners Not Filling Full Page Width

Product: SharePoint
Device & OS: not provided
Scenario: Creating and sending email newsletters or communications using SharePoint pages.
Observed behavior: Banners that previously filled the email width now display gaps on the edges, except for the top banner, in both the email preview and the final delivered message.

Before you start

Ensure you have the necessary edit permissions for the affected SharePoint page to access its version history and apply restorative changes.

Solution 1Recommended

Restore a Previous Version of the SharePoint Page

Reverting the SharePoint page to an earlier state can quickly resolve banner formatting errors caused by recent template updates or accidental edits.

SharePoint automatically saves versions of your pages as you make edits. By restoring a version from a date when the banners displayed correctly, you can bypass recent layout glitches.

Open Version History

Navigate to the affected SharePoint page. Click on 'Page details' on the top command bar, then select 'Version History'.

Select an Earlier Version

Look through the list of saved versions and select one created before the banner width issue started occurring.

Restore and Test

Click the 'Restore' button to revert the page. Once restored, preview the email again to confirm the banners fill the full width.

Restore a Previous Version of the SharePoint Page

Backup Recent Content: Restoring an older version will overwrite any text or elements added recently. Copy any new content to a separate document before proceeding.

Solution 2

Contact Microsoft 365 Support

If restoring an older version does not resolve the issue, a backend update or configuration change by Microsoft may be responsible.

Frequently Asked Questions

Why are my SharePoint banners suddenly showing gaps on the sides?

This issue is often caused by recent backend updates rolled out by Microsoft, accidental changes to the page section layouts, or web part template glitches that constrain image dimensions.

Will restoring a previous page version delete my recent content?

Yes, restoring a previous version will revert the entire page to how it looked at that specific time, removing any newly added text or web parts. It is highly recommended to back up your recent additions before restoring.

How do I ensure images span the full width in a SharePoint page?

To achieve a full-width appearance, ensure your section layout is set to 'Full-width section' and use the Image or Hero web part. Also, verify that the image resolution is high enough to span wide screens without being constrained by its native dimensions.
