Microsoft 365 Copilot Chat is the secure, AI-powered assistant already included in your Business Premium or Enterprise plan—ready to save you time, tap into your internal data, and scale across your business safely
If your organisation is using Microsoft 365 Business Premium, E3 or E5, there’s a powerful new productivity tool sitting quietly in your stack: Copilot Chat. It’s secure, built-in, and doesn’t cost you a cent extra.
Think ChatGPT—but smarter about your work, your data, and your security requirements.
Whether you’re drafting emails, summarising meetings, hunting down buried files or untangling a spreadsheet, Copilot Chat is designed to help you get more done, faster.
And if you’re already using Teams, Outlook, Word or SharePoint? You don’t need to change a thing. It’s woven directly into the tools you’re already working with—just open a new tab at copilot.microsoft.com, and start chatting.
Unlike generic public AI tools, Copilot Chat is built with enterprise security at its core:
No data sharing with OpenAI or public models
Everything stays within Microsoft’s compliance boundary—Copilot doesn’t leak your information back to the model or the internet.
Data stays inside your Microsoft 365 tenant
All content is scoped to what you already have access to—Copilot respects the same permissions as your Teams, Outlook, and OneDrive.
Compliance, privacy and transparency
Microsoft has made its AI tooling compliant with ISO 27001, SOC 2, GDPR, and local data residency regulations—something no third-party AI tool can promise out of the box.
This isn’t a disconnected chatbot scraping the web. Copilot Chat understands your business context:
Search your Outlook inbox and summarise threads or find old attachments
Access Teams chats and pull out decisions, updates or action items
Dig into SharePoint or OneDrive files, even surfacing insights from PDFs and Excel files
Track meetings, calendars, and projects with full access to your Microsoft Graph
It becomes a daily-use tool because it speaks your business language—and remembers your work.
One of the most overlooked facts? Copilot Chat is free if you’re using:
Microsoft 365 Business Standard
Microsoft 365 Business Premium
Microsoft 365 E3 or E5
Office 365 E3 or E5
With these plans, you get access to the web app (copilot.microsoft.com), Microsoft Teams integration, Windows Copilot, and more—no $30/month user licence needed.
If you want more advanced functionality—like inline help in Word or Excel, or Copilot reading your full Microsoft Graph context—you can upgrade with the Copilot for Microsoft 365 licence add-on.
But for most day-to-day users, the base Copilot Chat is already a game-changer.
There’s no shortage of AI tools flooding the market. But Copilot Chat has a few advantages that make it the clear choice for business-wide rollout:
Already included in your licensing (no hidden costs)
Secure by design, with full admin controls and compliance coverage
Embedded in your existing Microsoft tools—no training curve
Understands your actual work—not just public web content
Rather than trying to control or restrict shadow AI use in your teams, you can empower staff with something better, safer, and already integrated.
