A Microsoft 365 Copilot safe use guide for employees should make everyday decisions clear: which account to use, what information is appropriate for a task, and how to check the result before sharing or acting on it. A broad warning to “be careful” is not enough. Employees need practical examples and a simple route for questions or mistakes.
Copilot’s protections do not replace your organization’s security settings, access controls, or policies. Microsoft recommends using security and governance controls as part of a Copilot deployment. Administrators can use the Microsoft guidance on Copilot security and governance to inform those decisions.
Start with the approved account and experience
Tell employees exactly which Copilot experience they may use for work and how to recognize the organization-approved account. If they are unsure whether they are signed in with a work account or using an approved experience, they should stop before entering business information and ask their manager or IT team.
This distinction matters because work information should only be used in tools and accounts authorized by the organization. Do not assume that every product or account with the Copilot name has the same protections, settings, or access to company information.
Give employees clear examples of permitted use
Describe common lower-risk tasks that are allowed under your organization’s rules. Examples may include summarizing an approved internal document the employee is authorized to access, drafting a routine message from non-sensitive notes, or organizing information for a meeting. Employees should still check the result before relying on it.
Set boundaries for tasks involving confidential information, regulated records, external communications, or decisions that affect people. A task that seems routine can become sensitive when its source material includes private details or when the output will be used for a consequential decision.
- Usually appropriate when authorized: Drafting a general internal announcement, outlining a presentation from approved materials, or summarizing a non-sensitive procedure.
- Pause and check first: Using customer, patient, client, financial, personnel, or confidential business information; generating content for an external recipient; or using an answer to make a high-impact decision.
- Do not enter: Passwords, authentication codes, private keys, or information your organization’s policy specifically prohibits sharing with the tool.
Make clear that examples are not a substitute for the organization’s classification rules. If an employee cannot tell whether information is sensitive, the safe default is to leave it out and ask.
Set specific rules for sensitive business information
List sensitive information in language employees recognize. This may include customer contact and account details, patient information, legal matter or client details, financial records, employee records, unpublished business plans, credentials, and security information. Explain which categories are allowed in an approved Copilot experience, which require authorization, and which must not be entered.
Do not tell staff that information is automatically safe simply because they are using a work account. Microsoft describes enterprise data protection for eligible work experiences, including how prompts and responses are handled and whether they are used to train foundation models. Employees should use the organization-approved experience and follow its data rules; Microsoft’s enterprise data protection overview provides details about those protections.
Healthcare: Treat protected health information as restricted unless the organization has approved the specific use and confirmed that the necessary protections and arrangements are in place. Do not paste patient details into an unapproved tool or account. When in doubt, use de-identified information only if your organization permits it, or ask the privacy or security contact.
Legal work: Client confidentiality and matter restrictions still apply. Employees should not place client or matter information into Copilot unless their organization has authorized that use and any applicable client or matter requirements have been considered. A lawyer should review legal analysis and work product before it is used or shared.
Financial services: Follow firm policies for confidential customer and financial information. Verify generated analysis and communications, and route regulated or client-facing work through the firm’s required review and supervision processes. FINRA’s discussion of how member firms use generative AI can help firms consider oversight in this setting.
Explain what Copilot can access
Microsoft 365 Copilot can work with information an employee is permitted to access in Microsoft 365. That does not mean every employee can see every file. It does mean that existing access permissions matter: information that is already shared too broadly may be easier to discover or use than intended.
Employees should only request or use information they are authorized to see. Administrators should review permissions and sharing practices as part of deployment. For practical background, see this guide to reviewing SharePoint permissions for Microsoft 365 Copilot.
Require a repeatable check before using an answer
Copilot can produce polished language that still contains errors, missing context, or unsupported conclusions. Ask employees to use a consistent review process rather than treating a confident tone as proof.
- Open the source. Check the cited or underlying document rather than relying only on a summary.
- Confirm key details. Verify names, dates, amounts, terms, and other facts against an authoritative source.
- Check context and calculations. Look for missing qualifications, outdated information, incorrect assumptions, or arithmetic that should be recalculated independently.
- Get qualified review. Have the appropriate subject matter expert review content before high-impact decisions, legal work, financial analysis, patient-related use, or external distribution.
- Own the final work. The employee remains responsible for the material they approve, send, or use.
Employees should also know when not to use a response. If the source is unclear, the answer conflicts with trusted information, or the consequences of an error are significant, they should pause and escalate rather than guess.
Include a simple incident-reporting process
Tell employees what to do if they accidentally enter or share sensitive information. The guide should name the internal contact or reporting channel, explain that staff should report promptly, and say what details to include, such as the tool used, the type of information, and what happened. Do not ask employees to investigate the incident themselves or assume that deleting a prompt resolves it.
Administrators should pair employee guidance with practical controls: review permissions and oversharing, configure available protections, establish expectations for prompt and response retention, and make the reporting route easy to find. Organizations can also use a staged rollout and training plan; the site’s guide to measuring Microsoft 365 Copilot adoption offers related considerations.
Frequently asked questions
What information is safe to enter into Microsoft 365 Copilot?
Use only the organization-approved account and information permitted by your company’s policy. Non-sensitive, approved work material may be appropriate for routine tasks. Sensitive information requires authorization, and prohibited information should never be entered.
Can employees put customer, patient, or client information into Copilot?
There is no blanket yes. The organization must approve the specific tool, use, and information category, and employees must follow applicable internal requirements. Patient, client, and customer information should be treated as sensitive unless the organization clearly authorizes the use.
Does Microsoft 365 Copilot use prompts or business data to train AI models?
Microsoft’s enterprise data protection documentation explains how eligible work experiences handle prompts and responses, including their use for model training. Employees should confirm they are using the organization-approved experience and refer to the current Microsoft documentation and company policy.
What should I do if I accidentally enter sensitive information?
Report it promptly through your organization’s designated security, privacy, or incident channel. Include what information was involved and which experience you used. Follow the response team’s instructions rather than trying to manage the issue on your own.
