Microsoft Copilot Policy Template: What to Cover in 2026

Last updated: June 2026 · Guardrail Studio

Microsoft 365 Copilot isn't just another chatbot — it reads your real files, email, and chats. That makes it powerful, and it makes a Copilot-specific policy essential. Here's what to cover, the permissions trap to avoid, and a free starter clause.

Why Copilot needs its own policy clause

ChatGPT only knows what a user types into it. Copilot is different: it operates inside your Microsoft 365 tenant and can draw on anything the user already has permission to see — documents, inboxes, Teams chats, SharePoint sites. That's a different risk profile. The danger isn't only careless pasting; it's Copilot confidently surfacing sensitive content from a folder that was over-shared years ago.

The Copilot "oversharing" problem

Copilot inherits your existing permissions. If half the company can technically access the HR drive or a confidential deal folder, Copilot will happily summarize it for them on request. Most organizations have years of accumulated permission sprawl. So Copilot governance starts before the policy: review access, apply sensitivity labels, and lock down the sites that should never have been broadly shared.

What a Copilot policy must cover

Access scope — Copilot only reflects existing permissions; permissions hygiene is part of the policy.
Sensitive content — which sites, labels, and data types are off-limits to Copilot-assisted work.
Prompt hygiene — don't paste external confidential data into Copilot chat; treat outputs as drafts.
Human review — you own what Copilot produces; verify before it's shared or actioned.
Personal data — Copilot use involving personal data still falls under PDPA/GDPR.

[COMPANY] — Microsoft 365 Copilot Usage Policy (Starter)

1. SCOPE. Copilot may be used to draft, summarize, and analyze content you are
   already authorized to access. It does not grant new access rights.

2. PERMISSIONS. Copilot reflects existing permissions. Report any document or
   site you can access via Copilot that you shouldn't to [OWNER].

3. SENSITIVE DATA. Do not use Copilot to process content with the following
   sensitivity labels / sources: [list]. Do not paste external confidential or
   personal data into Copilot chat.

4. REVIEW. You are responsible for Copilot output. Verify facts and figures;
   never share or act on unreviewed output.

5. PERSONAL DATA. Use involving personal data must comply with our data-protection
   obligations (PDPA/GDPR).

6. INCIDENTS. If Copilot exposes data it shouldn't, tell [CONTACT] immediately.

Copilot and data-protection law

Keeping data inside your tenant helps, but it doesn't end your responsibilities. Personal data in prompts and outputs is still governed by the PDPA (Singapore) and GDPR. You still need a lawful basis, retention discipline, and the ability to show how Copilot use is controlled — which is exactly what a policy and a risk register provide.

Frequently asked questions

Why does Copilot need a different policy to ChatGPT?

Because Microsoft 365 Copilot works on your actual tenant — it can read the files, emails, and chats a user already has access to. The risk isn't just what staff paste in; it's what Copilot can surface from poorly-permissioned SharePoint sites and shared drives. The policy has to address access scope, not just inputs.

Does Copilot train on our company data?

Microsoft states that 365 Copilot does not use your tenant data to train its foundation models, and processes within your compliance boundary. That's better than a free public tool — but it doesn't remove your obligations around access control, sensitive-data labelling, output review, and data-protection law.

What's the fastest way to govern Copilot?

Tighten access permissions and sensitivity labels first, then publish a short Copilot clause in your AI policy and train staff. Guardrail's AI Policy OS gives you the policy, training, and register to do all three quickly.
