Viva Engage: New blocking controls for posts, comments, and replies based on themes

Viva Engage will introduce theme moderation to block posts, comments, and replies based on monitored themes, starting February 2026. Blocked content won’t publish, with exceptions for leaders and admins. AI detects themes, and no action is required before rollout, though admins should review settings and themes. Introduction We’re adding the ability for Viva Engage theme moderation to block posts, comments, and replies based on monitored themes. This provides stronger control over sensitive or inappropriate topics. This message is associated with Microsoft 365 Roadmap ID 513277. When this will happen: General Availability (Worldwide): Rollout begins early February 2026 and completes by late March 2026. How this will affect your organization: Who is affected: Viva Engage admins and corporate communicators who use theme moderation in the advanced moderation section of the Communications Dashboard.
