What is Microsoft Copilot?
Microsoft Copilot is an AI assistant built into Microsoft 365 apps including Word, Excel, PowerPoint, Outlook, and Teams. It uses large language models (similar to ChatGPT) combined with your organisation's data to help you work more efficiently.
Unlike standalone AI tools, Copilot understands your context. It can reference your emails, documents, calendar, and Teams conversations to provide relevant suggestions and complete tasks.
Copilot knows your data
This is both the power and the responsibility. Copilot can reference anything you have access to in Microsoft 365, which makes it incredibly useful but also means permissions and sensitivity labels matter more than ever.
Copilot in Outlook
Email is where many professionals spend hours each day. Copilot can dramatically reduce this time:
- Draft emails: Describe what you want to say and Copilot writes the email. "Write a follow-up email to John about the project timeline, keeping it professional but friendly."
- Summarise threads: Ask Copilot to summarise long email chains so you can quickly catch up.
- Adjust tone: Make an email more formal, more concise, or more friendly with a single click.
- Schedule suggestions: Copilot can suggest meeting times based on participants' availability.
Real-World Example
Instead of spending 10 minutes crafting a response to a client complaint, you can prompt Copilot: "Write a professional response acknowledging their concern about the delayed shipment, apologise, and offer a 10% discount on their next order." Copilot generates a well-structured response in seconds.
The admin staff who used to spend hours on email now spend minutes. They tell us they feel like they have got their afternoons back.
Copilot in Word
Writing documents becomes faster and easier with Copilot:
- Generate first drafts: Create proposals, reports, or articles from a simple prompt.
- Rewrite content: Improve clarity, adjust tone, or make text more concise.
- Create from files: Generate a document based on another file, like turning meeting notes into a formal report.
- Add content: Ask Copilot to expand on a section or add relevant details.
Copilot in PowerPoint
Creating presentations is often tedious. Copilot changes this:
- Generate presentations: Create a complete slide deck from a Word document or a simple prompt.
- Add slides: "Add a slide about our Q3 revenue growth with a chart."
- Improve design: Copilot can suggest better layouts and formatting.
- Create speaker notes: Generate talking points for each slide.
Start with a Word document
The best PowerPoint results come from giving Copilot a well-structured Word document to work from. Write your key points in Word first, then ask Copilot to generate a presentation from it.
Copilot in Teams
Teams meetings become more productive with Copilot:
- Meeting summaries: Get automatic summaries of meetings you attended or missed.
- Action items: Copilot identifies and lists action items from discussions.
- Catch up: Ask "What did I miss?" and get a summary of recent conversations.
- Real-time assistance: During meetings, ask Copilot questions about the discussion.
The meeting summaries alone justify the cost for busy managers. No more scrambling to remember what was agreed, it is all captured automatically.
Best Practices for Using Copilot
1. Be Specific in Your Prompts
The more context you provide, the better the output. Instead of "Write an email," say "Write a brief, professional email to our supplier requesting a quote for 500 units of product X, delivered by end of month."
2. Iterate and Refine
Copilot's first output is not always perfect. Use follow-up prompts to refine: "Make it shorter," "Add more detail about pricing," or "Use a more casual tone."
3. Always Review Output
AI can make mistakes or miss context. Always review and edit Copilot's output before sending or sharing.
Using Copilot Securely, and Why That Matters
Copilot is powerful precisely because it has access to your data. That is also why it has to be deployed carefully. For organisations handling patient records, client financials, legal matters, or anything else that lives under the Privacy Act, Copilot introduces new questions that a generic rollout will not answer.
Copilot sees what you can see
If you have access to a SharePoint library you should not, Copilot will happily surface that content when asked. Many organisations discover permission problems for the first time when they deploy Copilot.
1. Copilot Inherits Your Permissions, Good or Bad
Copilot respects the permissions already set in Microsoft 365. That cuts both ways. If a user has access to a SharePoint library containing sensitive files they should not have seen, Copilot will happily surface that content when asked the right question. Many organisations discover permission drift the hard way, through Copilot. Before rollout, a full audit of SharePoint, OneDrive, and Teams permissions is not optional.
2. Data Residency and Your Compliance Obligations
Copilot processes prompts through Microsoft's Azure infrastructure. For Australian healthcare and Privacy Act obligations, understanding where prompts, grounding data, and outputs are processed is a conversation worth having before rollout, not after. Microsoft publishes detailed guidance on data handling, but translating that into a defensible compliance position for your organisation takes work.
3. Sensitivity Labels and Information Protection
Microsoft Purview Information Protection lets you classify documents (Confidential, Patient Data, Legal Privilege, and so on) and control how Copilot handles them. Without sensitivity labels in place, Copilot treats all content equally. With them configured properly, you can prevent Copilot from summarising, quoting, or referencing classified content in inappropriate contexts.
The single biggest risk with Copilot is not the technology. It is a well-meaning staff member pasting confidential information into a prompt without thinking about where that data goes.
4. Prompt and Output Retention
Copilot prompts and responses can be retained by default for audit and compliance purposes. That is useful for governance. It is also something your staff should know, because a casual prompt typed into Copilot is not the same as a private thought. Clear AI use policies matter.
5. Healthcare and Clinical Use Cases
For medical practices, aged care providers, and allied health, we recommend an additional layer of review. Copilot in Outlook can dramatically speed up admin work. Copilot on a record containing patient identifiers, conditions, or clinical details should be treated with the same care as any other handling of that data. Policy, training, and technical controls all play a part.
Healthcare needs extra care
We help healthcare clients deploy Copilot with additional controls: sensitivity labels for patient data, restricted access to clinical systems, and training specific to Privacy Act obligations.
6. Policy and Training Matter More Than Technical Controls
The single biggest risk with Copilot is not the technology. It is a well-meaning staff member pasting confidential information into a prompt, or asking Copilot to summarise a document they would not email externally. An acceptable use policy specific to AI, supported by short, regular training, is worth more than any licensing configuration.
Before You Roll Out Copilot: A Ready-to-Deploy Checklist
If you can tick these off, you are ready. If you cannot, start there.
- Audit SharePoint, OneDrive, and Teams permissions
- Review sensitivity label strategy and deploy Microsoft Purview if needed
- Define an AI acceptable use policy for your organisation
- Train staff on what should and should not go into a Copilot prompt
- Document your data residency and retention position
- Decide which roles and teams get Copilot first, and measure the outcomes
- Review your Privacy Act and sector-specific obligations against your Copilot deployment plan
