Microsoft Viva Amplify now supports custom themes and fonts from SharePoint’s Brand Center, enabling branded, consistent communications across channels. Default SharePoint themes apply automatically, with options to override. Custom fonts require deployment via endpoint management. Rollout begins mid-July 2025, with no tenant-level disable controls.
Introduction
Microsoft Viva Amplify now supports custom themes and fonts published to SharePoint’s Brand Center, empowering communicators to align campaigns with organizational branding and maintain visual consistency across channels like Outlook and SharePoint.
Custom fonts allow organizations to apply their own typography to Viva Amplify communications. These fonts are managed via SharePoint’s Brand Center and can be applied to campaigns for a consistent and professional appearance.
Custom themes enable personalization of communications by applying branded color palettes. Whether sending newsletters, announcements, or event updates, custom themes help ensure your message is polished and on-brand.
This update is associated with Microsoft 365 Roadmap ID 498322.
