Assessment Reasoning
The update introduces a new method for accessing additional Copilot agents in Excel via the header menu, changing user workflow slightly. Admin impact is limited to awareness and updating internal guidance, as no configuration or policy updates are required. User impact is moderate because the path to Copilot changes for some tasks, requiring communication and possible support queries. Urgency is moderate since the rollout has started and completes by end of August, but no admin action is mandatory beyond communication.
