Microsoft Adds Copilot 'Explain This' Feature to Classic Outlook

Microsoft is rolling out a new Copilot AI feature called "Explain This" to the classic Outlook app on Windows 10 and Windows 11. This feature allows users to select any text within an email and receive a context-aware explanation based on the entire email's content. This update brings modern generative AI capabilities directly into the legacy desktop client, helping users quickly understand complex terms or references without leaving their workflow. It demonstrates Microsoft's commitment to supporting the classic Outlook client alongside the new web-based Outlook. The rollout is expected to be completed by the end of September, with most users gaining access by early September. Users will have control over when and how the AI assists them, integrating productivity and decision-making into their daily email management.
