What is Microsoft 365 Copilot?
Copilot is an AI assistant built into the Microsoft 365 apps you already use: Outlook, Word, Excel, PowerPoint, Teams, and OneNote. It can draft emails, summarize meetings, build spreadsheets, search across company files, and answer questions from your business data.
Unlike public AI tools, Copilot respects your existing Microsoft 365 permissions. If a user cannot access a file directly, Copilot will not surface it to them. That makes it one of the safer places for a small business to start with AI — but only if your permissions are already tidy.
Draft & summarize
Emails, documents, meeting notes, and slide decks.
Respects permissions
Only sees what the user already sees.
Built for teams
Works inside Outlook, Teams, Word, Excel, and PowerPoint.
Which plan do you need?
Copilot requires a qualifying Microsoft 365 Business or Enterprise plan. The two most common small-business options are Business Standard and Business Premium.
| Feature | Business Standard | Business Premium |
|---|---|---|
| Copilot add-on available | Yes | Yes |
| Desktop Office apps | Yes | Yes |
| Web/cloud email & files | Yes | Yes |
| Microsoft Defender for Business | — | Included |
| Microsoft Intune device management | — | Included |
| Conditional access policies | — | Included |
| Azure AD P1 features | — | Included |
| Best for AI security | Basic | Recommended |
KCM recommendation
If you are buying Copilot, choose Business Premium. The included Defender and Intune make it far easier to enforce security guardrails before staff start feeding company data into AI prompts.
Security governance for Copilot
Copilot is only as safe as your Microsoft 365 tenant. Before turning it on, clean up the permissions and data your staff can already reach.
Audit file and folder sharing
Remove public links, anonymous access, and broad ‘everyone’ sharing from SharePoint and OneDrive. Copilot can summarize anything the user can open.
Turn on sensitivity labels
Label documents as Internal, Confidential, or Restricted. Pair labels with DLP policies so Copilot cannot quote or draft from protected content.
Restrict guest access
Guests in Teams or SharePoint may see more than you think. Review guest memberships and remove expired or unnecessary accounts.
Train staff on shadow AI
Tell people what Copilot is allowed to do and what it is not. A clear acceptable-use policy prevents staff from copying sensitive data into public AI tools.
A safe rollout plan
Start small, measure value, and expand. Here is the rollout sequence we recommend for small businesses with 5 to 100 users.
Pilot with a small group
Pick 3–5 users who already live in Outlook, Teams, and Word. Give them Copilot and collect feedback after two weeks.
Clean up permissions
Fix the sharing, guests, and labels before rolling Copilot out to the rest of the company. This is the step most businesses skip.
Publish an AI policy
Write one page: what staff can ask Copilot, what data they can paste, and what must stay out of any AI tool.
Train in 30-minute sessions
Show real examples: summarize a long email thread, draft a proposal from notes, build a spreadsheet from a Word table.
Measure and expand
Track time saved, draft quality, and security incidents. Add licenses department by department once you see clear value.
Copilot readiness checklist
Tick these boxes before you buy licenses. If any are unchecked, fix them first.
