Assessment Reasoning
This is a new Outlook feature that allows automatic spell checking before sending emails. It mainly affects end users and help desk teams due to slight UI and workflow changes. Admin effort is minimal because rollout and configuration are user-driven, though support documentation may need light updates. Rollout is scheduled for late 2026, so current urgency is low and primarily informational.
