Microsoft SharePoint is introducing a new Preview mode for Pages and News posts, allowing users to see how content appears on different devices. The rollout will start in late March 2025 for Targeted Release and mid-April 2025 for General Availability. No admin action is required, but user notification and training updates are recommended.
