The complete guide to Microsoft Copilot: how to really get the most out of it at work (2025)

Artificial intelligence is transforming the way we work. Among the most powerful solutions—fully integrated for business use— Microsoft Copilot is now one of the most advanced tools to boost productivity, collaboration, and work quality within Microsoft 365.

In this guide you’ll learn what Microsoft Copilot is, how it works, the most useful features in Word, Excel, Outlook, Teams and PowerPoint, and—most importantly—how to use it effectively through strong prompts and best practices for companies and professionals.

What is Microsoft Copilot?

Microsoft Copilot is Microsoft’s AI assistant integrated into the apps most used at work: Word, Excel, Outlook, Teams, PowerPoint, OneNote and Windows.

Unlike a simple chatbot, Copilot:

• uses your organization’s data from SharePoint, OneDrive, email and Teams chats—within existing permissions
• understands your work context
• generates content, analysis and tailored automation
• works inside Microsoft 365—no need to switch tools

It’s designed to bring generative AI into everyday operations, acting as a real digital accelerator for organizations.

Why Microsoft Copilot matters for business productivity

Thanks to its ability to analyze documents, emails and business data, Copilot helps you:

• cut operational time by up to 40%
• automate repetitive tasks
• speed up internal and external communication
• improve content quality
• get insights without technical skills

For many companies, Copilot is the first concrete step toward structured adoption of generative AI at work—integrated with Microsoft security and governance.

How to get the most out of Microsoft Copilot: best practices (2025)

A strong prompt includes:

More specificity = better results.

2. Organize your business data

Copilot works better when data and documents are structured. Tips:

A good setup ensures security, governance, and more accurate results.
