How does this affect me?
Classic theming is not honored with the modern, refreshed look, which is becoming mandatory for model-driven apps in April 2026. The supported theming replacement with the modern look is custom modern themes, which gives makers the ability to:
- Apply a cohesive color scheme across the app based on a single base color, including hyperlinks, primary buttons, active tab indicators, row selection, and hover effects.
- Customize the app header background and text colors, including hover, pressed, and selected states.
- Set a custom logo for the app header to reinforce organizational branding. Note: Custom logo support in the modern theme XML is currently rolling out and will be available in all regions by the end of April 2026.
- Override the default font used throughout the application.
What action do I need to take?
To take advantage of custom theming, we recommend doing the following:
- If your organization was using classic themes, create a new custom theme XML web resource that reflects your branding. Follow the steps in the documentation to apply it to your environment.
- Update internal documentation and training materials to reference the new custom theming approach instead of classic theming.
- Report any issues or unexpected behavior through Microsoft Support so we can investigate.
