Copilot / Copilot Accounts & Source Grounding
Copilot: handle a missing work file without guessing
Record the file title, expected location and the access error. Confirm you can open it normally before troubleshooting Copilot access.
Environment and inputs: Copilot user guide · Feature and source access depend on the active account, app and organization settings. Optional file or app steps have a text-excerpt fallback. No fixed model version, price or usage quota is assumed.
What you will make
A practical Copilot guide to handle a missing work file without guessing. Use the sample input and prompt, then check the result. Use a fictional Microsoft 365 workplace task as the practice setting. Identify the file or excerpt that supports the requested result.
Prepare the source and scope
Record the file title, expected location and the access error. Confirm you can open it normally before troubleshooting Copilot access. Open your available Microsoft Copilot experience and confirm whether it can read the intended work source.
Try this prompt
In Copilot, provide the prepared input, then send the following request. For real work, replace fictional details with approved facts.
Explain which evidence is missing for this question and draft a request to the file owner for the specific excerpt needed. Do not reconstruct the file's contents.Review the result
Verify the proposed request asks for a limited relevant passage and preserves organizational sharing rules. Record each correction and its supporting source.
If the answer is wrong or incomplete
A colleague's access does not prove your account has the same permissions. Resolve the actual source-access issue through its owner. If the active Copilot surface cannot access the file or app, paste an authorized excerpt into chat. Keep the same review criteria for the text-only workflow.
Practice and completion check
Repeat with one incomplete input. Check the answer against the review criteria, remove unsupported claims and save the prompt with its source version. This workflow has not been verified in a customer deployment.
