Solution 1Recommended

Understand Branding Limitations and Submit a Feature Request

Since customizing SharePoint automated news emails is currently unsupported natively, the recommended action is to formally request this feature from Microsoft.

Microsoft 365 Custom Themes are designed to brand the top navigation bar and select UI elements across web applications. However, they do not currently extend their CSS or branding assets into system-generated email templates like SharePoint's 'News You Might Have Missed'.

Because this is a strict system limitation rather than a configuration error, there is no direct toggle to fix it. Microsoft prioritizes feature updates based on user demand through their feedback portal.

1
Acknowledge the system limitation

Understand that the inability to brand 'News You Might Have Missed' emails is an existing limitation in the Microsoft 365 environment, and no local settings can override it.

2
Navigate to the Feedback Portal

Open your web browser and go to the official Microsoft SharePoint Feedback Portal online.

3
Submit a new feature request

Click to submit a new idea. Clearly describe the need to apply Microsoft 365 Custom Themes and organizational branding to SharePoint-generated emails so that the development team can consider it for future updates.

Community Upvotes: Before submitting a new request, search the feedback portal to see if another user has already requested this feature. Upvoting an existing, highly visible request often yields faster results.

Frequently Asked Questions

Can I use Power Automate as a workaround for SharePoint email branding?

Yes, for standard alerts. While you cannot change the native 'News You Might Have Missed' digest, you can disable it and use Microsoft Power Automate to create custom workflows that send fully branded HTML emails triggered by new SharePoint news posts.

Where do Microsoft 365 Custom Themes actually apply?

Custom Themes generally apply organizational logos and colors to the top navigation bar across Microsoft 365 web applications, including SharePoint, Outlook on the web, and the main Office portal, rather than to outbound automated emails.

Will third-party email branding tools work on these SharePoint emails?

No. Because the 'News You Might Have Missed' emails are generated and sent directly by Microsoft's backend servers, standard third-party email signature and branding tools that intercept standard Exchange mail flow typically cannot alter them.
