Microsoft pulls the plug on Outlook’s AI inbox assistant

AI-summarised brief · reviewed before publication

Microsoft has discontinued the AI‑powered inbox assistant in Outlook after a brief rollout, removing the feature from both desktop and web versions for all users. The tool, which used large‑language‑model prompts to suggest replies, prioritize messages and draft summaries, was introduced earlier this year as part of Microsoft 365’s broader AI push. Internal testing reportedly revealed inconsistent performance and user confusion, prompting the company to halt deployment and issue a statement that the assistant would be “temporarily unavailable while we refine the experience.” The removal affects Outlook for Windows, macOS, iOS, Android and Outlook on the web, and Microsoft has pledged to reintroduce an improved version later this year. Customers can expect clearer guidance and tighter integration with Teams soon.
