Microsoft is extending the use of artificial intelligence (AI) tools in its Outlook email platform for corporate users. The Microsoft 365 Copilot tool, billed as “your everyday AI companion,” will assist users in crafting concise and error-free emails while also summarizing lengthy email threads to suggest quick replies.

Users with Microsoft 365 Personal or Family subscriptions will benefit from advanced AI assistance through Microsoft Editor, an intelligent writing assistant that will offer suggested edits for clarity, conciseness, inclusive language, and more, enhancing the professionalism of their emails.

The company has announced that the tool will be available to more corporate clients starting on November 1, following months of testing with customers including Visa, General Motors, KPMG, and Lumen Technologies.

In March, Microsoft unveiled its plans to integrate AI into its core productivity tools, such as Outlook, PowerPoint, Excel, and Word. The introduction of the AI-powered ‘copilot’ is based on the same technology used for ChatGPT and is aimed at transforming how millions of users conduct their daily work.

Beyond email composition, Microsoft 365 users can also utilize AI to summarize meetings, create suggested follow-up action items, request specific Excel charts, and quickly convert Word documents into PowerPoint presentations.

Corporate customers will also have access to Microsoft 365 Chat, previously known as Business Chat, which acts as a personalized assistant by scanning the internet, employee emails, meetings, chats, and files.

This expansion comes less than a year after the public release of ChatGPT by OpenAI, a viral AI chat tool known for its ability to generate original essays, stories, and song lyrics in response to user prompts. The success of ChatGPT prompted a tech industry competition to develop and integrate similar AI tools into their products. Companies like Google have followed suit, introducing AI features to their productivity tools like Gmail, Sheets, and Docs.
