If Copilot answers a question about your project with a generic explanation, start by checking whether the conversation can use your work data. A fluent answer is not proof that Copilot searched your tenant, and a generic answer does not by itself prove a permission failure.
This guide covers Microsoft Copilot in a work or school account, not consumer Copilot or a custom Copilot Studio agent. Official guidance checked October 14, 2026.
Why work questions can receive general answers
The conversation might not be using work grounding, the requested source might be unavailable to your account, or the prompt may not identify the right document. A CRM record also does not become accessible merely because your company uses Microsoft 365: its integration and permissions must support the requested task.
Microsoft’s current grounding guidance describes a Work IQ on/off control in Chat, replacing the older Work and Web tabs. Work IQ lets eligible licensed users include authorized work information. With it off, attached content and permitted web information can still be used. If your organization is on an older interface, check the equivalent work-grounding control rather than looking for an identical layout.
There is no general administrator setting called “Microsoft Graph data sources: On” that fixes this symptom. Nor does assigning someone to an enterprise application in Entra assign that person a Microsoft 365 product license.
Test with one known document before changing tenant settings
- Check the identity and conversation scope. Confirm that Chat uses the intended work account. If Work IQ is available, turn it on for a question about your organization. If it is missing, ask the administrator to verify the actual entitlement rather than buying a personal subscription.
- Open the source yourself. Find a current, non-sensitive document that you already have permission to read. Check its title, location, and relevant passage. If you cannot open it, ask the owner for the minimum access required; Copilot is not a way around file permissions.
- Make the source explicit. Attach or reference the document using the controls available in your app. Ask, for example: “Using only this document, list the project deadlines and cite the section for each. If a deadline is absent, say so.” Do not ask Copilot to infer a private project from a vague name.
- Inspect the answer’s evidence. Open the citations and compare the dates and claims with the source. If it cites a different version, give the current file explicitly and repeat. If it cannot cite the requested passage, do not treat the answer as tenant-grounded.
- Separate retrieval from summarization. If an explicitly attached file works but an open-ended request cannot find it, report a discovery problem. If even the attached, supported file fails, investigate that file and the app experience before requesting a tenant-wide search change.
Users without paid work-wide grounding may still be able to provide content directly or use an approved, metered agent. Those are different access paths, not evidence that every chat can search all company data. Microsoft’s Copilot Chat FAQ explains these distinctions.
What an administrator or content owner should check
License assignment and permission are separate checks
Use Microsoft 365 admin center > Users > Active users > Licenses and Apps to inspect product assignment. Then have the file or site owner verify the user’s existing access. Neither licensing nor a successful generic chat grants permission to restricted documents. Use Microsoft’s assignment guidance for a confirmed licensing problem.
The file opens but search does not find it
Check the relevant site’s and library’s search visibility, and whether your organization has deliberately restricted discovery. Microsoft’s SharePoint search-visibility guidance explains those controls. Do not broaden access or undo an intentional restriction just to make an AI response work.
The document changed recently
Do not promise a fixed 15-minute refresh. SharePoint schedules crawling. If a schema change genuinely requires reindexing, the site owner can follow Microsoft’s targeted reindexing procedure: site settings, Search and offline availability, then Reindex site; a library can be reindexed separately in its advanced settings. Reindexing can add load and is not the default fix for a vague Copilot answer.
The problem survives the controlled test
Give support the app, account and tenant, approximate time, document location, expected passage, grounding control used, and whether direct reference succeeded. Redact confidential content unless the approved support process requires it. Keep the original source as the authority: work grounding can improve relevance but does not guarantee completeness or accuracy.
