SharePoint will enable tenant admins to centrally manage site branding via PowerShell, enforcing enterprise themes, disabling custom branding per site, auditing changes, and managing themes centrally by geo. Rollout begins late November 2025, with general availability by March 2026. Admins should prepare by reviewing PowerShell docs and updating processes.
