Copilot Chat works with web content and files provided directly by the user. Data remains secure and compliant with corporate requirements.
Artificial intelligence, productivity, digital transformation. These terms are everywhere. Yet many organizations are unaware that they already have an AI assistant built directly into their everyday Microsoft tools. No additional cost, no complex deployment, no dedicated IT project. It’s called Copilot Chat, and it’s ready to be used.
A powerful tool that is already available
“Microsoft quietly made Copilot Chat available.”
Most Microsoft 365 licenses (Business, E3, E5) already include Copilot Chat, a secure conversational assistant that can help users write, summarize, brainstorm, and analyze documents.
“Microsoft quietly made Copilot Chat available,” explains Stéphane Perrenoud, U-Consultant at UDITIS. “Many users either don’t know it exists or confuse it with ChatGPT.”
In practical terms, Copilot Chat works with web content and files provided directly by the user. Data remains secure and compliant with corporate requirements. An important point to note: this data is not reused to train Microsoft’s AI models.
Copilot Chat or Copilot for Microsoft 365: what’s the difference?
This is where confusion often arises. While Copilot Chat is included in existing Microsoft 365 licenses, its capabilities remain limited. To unlock the full potential of AI within Microsoft 365, organizations need Copilot for Microsoft 365, a paid add-on (approximately $30 per user per month) that significantly expands what AI can do.
The key difference lies in access to internal business data. With Copilot for Microsoft 365, the assistant can leverage the entire Microsoft Graph, including emails, Teams conversations, SharePoint documents, and calendars. “Summarize my unread emails,” “What was discussed during this morning’s Teams meeting?” or “Generate a report based on our internal documents” are requests that can only be handled with the full Copilot for Microsoft 365 license.
Another major distinction is native integration across Microsoft applications. Word, Excel, Outlook, PowerPoint, and Teams all include Copilot directly within the application itself, eliminating the need to switch windows or copy and paste content. The assistant works alongside users within their existing workflows.
Three use cases that quickly become habits
For teams discovering Copilot, several use cases naturally emerge within the first few weeks, even without extensive training.
- Email drafting and improvement is usually the first. It is universal, immediate, and effective. Rewriting a message, adjusting the tone, shortening text, or translating content delivers visible value within minutes. This is often the first “aha” moment.
- Content summarization quickly follows. Pasting a document or an email thread and requesting a five-point summary helps address a common challenge: information overload. It is simple to test and instantly useful.
- Brainstorming and structuring ideas often comes next. Presentation outlines, ideas, and checklists transform Copilot into a true thinking partner. At this stage, users begin integrating the tool into their daily work rather than viewing it as a novelty.
Teams and Outlook: where the value becomes tangible
“Copilot does 80% of the meeting recap. The remaining 20% still requires human judgment.”
One of the most anticipated capabilities is Teams meeting summarization. And it works, provided its limitations are understood. After a meeting, Copilot automatically generates a structured summary highlighting key points, decisions, follow-up actions, and speaker attribution. For a well-run project meeting, it can produce most of the meeting minutes automatically.
However, there are limitations. Copilot relies entirely on the meeting transcript. Poor audio quality, participants speaking over one another, or highly specialized terminology can reduce the quality of the results. It cannot see shared slides or written chat conversations. And in everyday French, performance remains less reliable than in English.
The key takeaway is simple: “Copilot does 80% of the meeting recap. The remaining 20% still requires human judgment.”
In Outlook, the productivity gains are often the ones that endure the longest. Faster email drafting, summarizing lengthy email threads after returning from vacation, and quickly identifying messages requiring action are just some of the benefits. Several UDITIS employees use Copilot in Outlook every day. “I couldn’t go back without it” is a common comment among those who have adopted the tool.
Word, Excel, and PowerPoint: a new way of working
In Word, Copilot can generate complete drafts from notes or instructions, rewrite content, adjust tone, or shorten text. Users spend less time writing from scratch and more time reviewing and refining, fundamentally changing how documents are created.
In Excel, Copilot helps analyze data and create formulas using natural language. “Which sales opportunities increased the most this quarter?” or “Create a trend chart for me” allows users to ask questions instead of building complex formulas, making advanced analysis accessible even to non-experts. At UDITIS, the integration between Copilot and Salesforce provides a practical example. Obtaining a list of commercial actions to follow up on is now significantly faster than manually reviewing each account and opportunity.
PowerPoint can generate complete presentations from a Word document or a simple prompt. Structure, content, and formatting are all created automatically, delivering substantial time savings. One important limitation remains: Copilot does not yet fully comply with a company’s visual identity guidelines. Content still needs to be adapted to internal presentation templates.
How long does it take to deliver real value?
Copilot adoption typically follows a predictable curve. The first two weeks are a discovery phase. Interest is high, usage remains superficial, and measurable gains are limited. Between the third and sixth week, regular users begin saving time on specific tasks. After approximately three months, new habits become established, and productivity gains stabilize.
The biggest success factor is not the technology itself. It is the support surrounding it: Targeted training based on real business use cases. Internal champions who share best practices. The freedom to experiment, make mistakes, and adjust. Without these elements, many teams remain stuck at the stage of “Interesting, but not essential.”
What’s next?
Organizations that successfully adopt Copilot for Microsoft 365 naturally begin asking a new question: What if AI could do more than answer questions? What if it could act, coordinate, and automate entire processes autonomously?
This is where AI agents come into play. We’ll explore that topic in a future article.
