Microsoft 365 Copilot: A Smarter Way to Work

Microsoft 365 Copilot is a powerful AI assistant integrated into Microsoft 365 apps like Word, Excel, Outlook, PowerPoint, and Teams. It's built using OpenAI’s models (like GPT-4) and Microsoft's own Graph data (your emails, calendar, documents, etc.), helping users be more productive directly within the tools they already use.

Microsoft Copilot can create content, give helpful suggestions, and automate tasks in tools like Windows, Microsoft 365, and GitHub. Microsoft is also adding new features and ways to use Copilot all the time.

What Makes Up Microsoft Copilot?

Microsoft says the Copilot system is built from three main parts that work together like a team:

1. Microsoft 365 Apps (Word, Excel, Teams, etc.)

This is where you use Copilot.

These are the apps you already know: Word, Excel, PowerPoint, Outlook, Teams, etc.
Here, you interact directly with the AI assistant.

For example:

In Word, you can ask Copilot to draft a report.
In Excel, you can ask it to analyze data and create a chart.
In Teams, you can ask it to summarize meeting notes.

Think of these apps as the “face” of Copilot—this is what you see and use every day.

2. Microsoft Graph (Your Organization’s Data)

This is the “brain” that stores and connects your data in Microsoft 365.

Microsoft Graph pulls together all your files, emails, calendar events, chats, and documents across the Microsoft ecosystem.
When Copilot needs information to answer a question or create something, it fetches data from Microsoft Graph.

For example:

You ask, “Summarize my last three emails with John.”
Copilot uses Microsoft Graph to find those emails across Outlook and Teams.

So, Graph acts like the “central library” for your data.

3. OpenAI Models (The AI Powerhouse)

This is the “engine” that thinks and creates.

Copilot uses powerful AI models from OpenAI, like:

ChatGPT-4 → To understand your requests, write text, answer questions.
DALL·E 3 → To create images from text prompts.

These models process your input and generate responses based on natural language understanding.

For example:

You ask, “Make a presentation about renewable energy.”
The OpenAI model understands your request and creates the first draft of slides.

This is like having a super-smart assistant who can write, think, and even draw.

When your organization sets up a Microsoft 365 subscription, a tenant is automatically created. This tenant securely holds your organization’s data within the Microsoft 365 service boundary. Microsoft 365 Copilot works as a shared service inside this boundary, accessing only the data that a user is authorized to see—like their emails, chats, and documents—using existing security, compliance, and privacy settings. When a user types a prompt in Copilot (for example in Word or PowerPoint), it processes the request with Microsoft Graph to fetch relevant data, sends the refined (grounded) prompt to the AI model, and then delivers a helpful response back to the user. All data is encrypted during this process. Copilot also respects role-based access controls, Conditional Access policies, and multifactor authentication (MFA), ensuring it cannot see or use data beyond a user’s permissions. Users can view or delete their Copilot chat history as needed.
