Assessment Reasoning
This update expands Teams webinar breakout room capacity to 1,000 participants and 100 rooms. Admin impact is moderate because no configuration changes are required, but internal documentation and training materials may need updating. User impact is higher as organisers gain new functionality affecting large webinars and engagement workflows. Urgency is moderate since the feature is already available without required admin action.
