Referencing the Right Resources
Copilot's answers are only as good as the data you point it to. Learn how to reference files, SharePoint sites, people, and web sources in your prompts.
Why referencing matters
Imagine asking a researcher to write a report — but you don’t tell them which documents to read.
They’ll write something, but it’ll be based on guesswork. Now imagine handing them the exact three documents they need. The report will be focused, accurate, and relevant.
That’s what referencing does in Copilot. When you point Copilot to specific files, emails, or people, you’re saying: “Look HERE for the answer.” Without references, Copilot searches broadly and might miss the most important information — or include irrelevant data.
Types of resources you can reference
| Resource Type | How to Reference | Best For |
|---|---|---|
| Files (Word, Excel, PPT, PDF) | Use / or Attach button to select from OneDrive/SharePoint | Grounding answers in specific documents |
| SharePoint sites | Reference a site URL or use / to find sites | Querying an entire knowledge base or document library |
| People | Use / followed by a person's name | Finding what someone shared, said, or worked on |
| Emails | Reference by subject, sender, or date in your prompt | Finding specific conversations or decisions |
| Meeting transcripts | Reference the meeting by name or date | Getting summaries or action items from meetings |
| Folders | Reference OneDrive or SharePoint folders | Scoping to a collection of related documents |
How to reference — step by step
Method 1: The slash command (/)
In Copilot Chat, type / to bring up a reference picker:
/then start typing a filename → select the file/then type a person’s name → reference their recent work/then type a site name → scope to a SharePoint site
Method 2: Attach files button
Click the paperclip / Attach icon in Copilot Chat to:
- Browse OneDrive files
- Browse SharePoint libraries
- Select specific documents to ground your prompt
Method 3: Natural language references
You can also reference resources naturally in your prompt text:
- “Based on the Q3 Marketing Report in the Marketing SharePoint site…”
- “Using Sarah’s email from last Tuesday about the product launch…”
- “From the Operations standup meeting yesterday…”
Real-world: Jordan's reference strategy
Jordan at Peak Solutions is preparing a proposal for a new client. Here’s how he uses references:
Step 1 — client context: “Summarise all emails from /Acme Corp contacts in the past month” Step 2 — pricing: “Using the /Enterprise Pricing Sheet.xlsx in the Sales SharePoint, list our standard pricing for the Premium tier” Step 3 — template: “Draft a proposal using /Proposal Template Q4.docx as the format, incorporating the client context and pricing above”
Each prompt references specific resources → Copilot stays focused → the proposal is accurate and consistent.
Choosing the right resource
| Scenario | What to Reference | Why |
|---|---|---|
| ”What’s our latest pricing?” | The specific pricing spreadsheet | Avoids outdated info from old files |
| ”What did the team decide about hiring?” | Recent emails + Teams chats about hiring | Gets decisions from the right conversations |
| ”Summarise the new policy” | The specific policy document | Avoids confusing old and new versions |
| ”What has Sarah been working on?” | Reference Sarah as a person | Pulls her recent files, emails, and activity |
| ”Research competitor trends” | Don’t reference work files — let web grounding help | Internal files won’t have competitor data |
Exam tip: The exam tests whether you can choose the RIGHT resource for the task. The wrong resource gives a wrong answer. For example: referencing last quarter’s report when asked about current performance, or referencing internal files when asked about industry trends.
When NOT to reference
Sometimes it’s better to let Copilot search broadly:
- Exploratory questions: “What’s been happening with Project X?” — let Copilot search across everything
- Web research: “What are the latest trends in supply chain management?” — web data, not internal files
- People search: “Who in my team has experience with Python?” — broad search is better than a specific file
