Microsoft will retire the Viva Engage user themes feature in January 2026 due to accessibility issues, removing personal theme settings and reverting users to the default theme. This change affects web, desktop, Teams, and Outlook users but not mobile apps. A new admin-led branding feature is planned. No admin action required.
Updated November 6, 2025: We have updated the timeline. Thank you for your patience.
Introduction
Microsoft is retiring the themes feature in user settings for Viva Engage. This change removes the ability for users to personalize their Viva Engage interface with custom themes. While usage of themes is low across Viva Engage tenants, this decision was made due to accessibility limitations in the current themes implementation, which conflict with future feature improvements. The retirement now helps pave the way for a new admin-led branding capability that is in development. This new feature will allow organizations to centrally configure visual elements such as logos, brand colors, and names. It is not yet available and will be communicated separately when ready.
