How to Stop Microsoft Copilot from Revealing Personal Information

Product: Microsoft Copilot

Scenario: Using Microsoft Copilot for research, drafting, or assistance and receiving output that contains unexpected private data.
Observed behavior: Copilot outputs personal and sensitive information that it has pulled from the user's account, connected services, browser context, or conversation history.

Before you start

Before troubleshooting, record the exact prompt you used and identify which specific Copilot experience you were using (such as Copilot in an Office app, Edge browser, or Windows) when the personal information appeared.

Solution 1Recommended

Review Privacy Settings and Connected Experiences

Check your Microsoft account and app settings to restrict the data Copilot can access from your connected services and organizational data.

Microsoft Copilot often draws context from active web pages, open documents, or data stored in your Microsoft 365 account to provide personalized answers. Adjusting these permissions limits what information is fed into the AI.

Identify the data source

Determine if Copilot was running in Edge (where it reads browser context), Word/Excel (where it reads document content), or Windows.

Access Privacy Settings

Log into your Microsoft Account Privacy Dashboard or open the specific Office app's settings menu.

Manage Connected Experiences

Navigate to 'Privacy' or 'Trust Center' settings, find 'Connected Experiences' or 'Organizational Data Access', and toggle off permissions that allow Copilot to access personal files.

Clear conversation history

Delete your recent Copilot conversation history to prevent the AI from referencing past sensitive data in future prompts.

Review Privacy Settings and Connected Experiences

Avoid sensitive prompts: Never type highly sensitive or confidential information into follow-up prompts while testing your new privacy settings.

Solution 2

Report the Privacy Incident for Investigation

If Copilot leaked sensitive data in a way that violates your organization's policies, escalate the issue to your IT administrator.

Frequently Asked Questions

Why does Microsoft Copilot know my course number and paper title?

Copilot can pull information from the context you provide it, such as an open document in Word, a webpage you are viewing in Edge, or files saved in your connected OneDrive account if Connected Experiences is enabled.

How can I clear my Microsoft Copilot chat history?

You can clear your chat history by clicking on the history icon or menu within the Copilot interface and selecting 'Clear all', or by visiting your Microsoft account privacy dashboard.
