Assessment Reasoning
This is a new accessibility enhancement allowing alternate text on OneDrive and SharePoint images shared in Teams. It requires no tenant configuration, though admins may wish to inform users and update accessibility documentation. User impact is moderate because the feature introduces an optional change in message composition behaviour. The rollout is scheduled for December 2026, meaning awareness and communication are the main actions needed.
