Artificial intelligence is now entering the heart of professional practices with Microsoft Copilot, directly integrated into the Microsoft 365 suite. This advance is not limited to adding a technical tool: it transforms the way employees interact with their data and applications. The integration is based on a secure infrastructure designed to meet business requirements, particularly in terms of data sovereignty and regulatory compliance. Copilot is therefore not just a powerful AI model: it is a solution encapsulated in a controlled environment, where confidentiality and security are guaranteed by Microsoft.

Access to Copilot is through a chat-type interface, available both in desktop applications and via the web. But the real power of Copilot lies in its connection to Microsoft Graph. This interconnection allows it to access all of a user’s professional data: documents, emails, calendars, meetings, contacts, and shared files, etc., and to link them together. Copilot can thus produce contextualized responses, adapted to the company’s reality and always subject to security rules and access rights in force. In other words, Graph opens the door to an intelligent and coherent use of all useful information, in real time.

You are the pilot, Copilot is your assistant

‍
Using Copilot is like learning a new language of collaboration: the language of the prompt. The formulation of requests becomes essential: the clearer and more contextualized the instruction, the more relevant the result. In this framework, the user remains the pilot and the AI their copilot. It follows instructions, enriches actions, and proposes alternatives. This practice – prompt engineering – becomes a key skill, consisting of refining one’s requests, testing different approaches, and keeping control over the quality of the information produced. Defining the objective, specifying the context, indicating the sources, and clearly formulating expectations (for example the format or level of detail) greatly increases the reliability of the result. But even under these conditions, biases or hallucinations may be presented by the AI, and it is important to understand that writing a perfect prompt may still be insufficient, and that iteration and reformulation remain the best assets to ensure reliable information.

‍Like any AI based on language models, Copilot is not infallible. It may generate plausible but inaccurate answers, or reflect certain biases from its training data. The user’s critical thinking therefore remains indispensable. The ability to question the AI, to compare several formulations, and to validate results must be considered a shared responsibility between the tool and its user.

Working differently in Microsoft 365

‍
It is in daily use that Copilot reveals its full value. Imagine an employee starting their workday. They begin with Word, where it is enough to formulate an idea or plan for Copilot to generate a first draft. A poorly written passage? The assistant instantly reformulates it. Several documents to synthesize? Copilot extracts the essentials and proposes a clear and coherent version. Writing a report then becomes a true collaboration with AI, saving precious time and allowing the employee to focus on what really matters.

On Outlook, the influx of emails could quickly become unmanageable. Copilot helps them get back on track: a few-line summary of a long email chain, pre-written responses adapted to the desired tone, automatic prioritization. Result: a more readable inbox, key information immediately identified, and more effective communication.

When preparing a strategic presentation in PowerPoint, there is no need to start from scratch. Copilot directly transforms a set of documents into a structured presentation, suggests coherent visuals, and adjusts the design based on the context. The workload shifts from formatting to substantive thinking, where human added value is strongest.

In a Teams meeting, the contribution is even more spectacular. Imagine: you receive a package and leave the room for five minutes. When you return, Copilot summarizes precisely what was said, by whom, and where the discussion stands. A colleague does not speak the same language? Copilot translates their voice in real time, making exchanges smooth and natural despite the language barrier. And once the meeting is over, it automatically generates a clear report, highlights the decisions made, and lists the actions to follow. More than a tool, Copilot becomes a true real-time collaboration partner.

The afternoon is devoted to data analysis in Excel. Copilot highlights trends invisible at first glance, links data together, and offers ready-to-use visualizations. The employee no longer needs advanced technical expertise: the AI directly provides the keys to turn data into concrete decisions.

Finally, Edge becomes the transversal access point to information. Copilot summarizes a web page, compares several sources, and puts them into perspective with the company’s internal documents. Browsing the Internet is no longer an isolated activity: it is enriched research integrated into the Microsoft 365 ecosystem.

Governance, security, and ethical aspects

‍
If Copilot opens new perspectives, its adoption must be accompanied by clear governance rules. Companies must define usage boundaries, frame access rights, and establish validation processes.It is also crucial to implement an internal AI policy: a framework that defines how employees should use Copilot, which practices to encourage, and which limits to respect. The ethical dimension remains central: confidentiality, transparency, and bias management must be guaranteed. Copilot is not just an operational tool: it is a strategic technology that requires responsible governance.

‍‍
By integrating into the daily work environment, Copilot goes beyond the simple role of a digital assistant. It proposes a new way of organizing the production and use of information. The challenge for organizations is now to support this evolution: training employees, establishing adapted governance, and integrating Copilot into their overall strategy. Used methodically and thoughtfully, it can become a major lever of competitiveness and prepare the company for a future where artificial intelligence will be at the heart of performance.
At eaQbe, we train employees in the use and evolution of Copilot, to help them get the best out of it in their daily work and to support the digital transformation of their organization.
