What it is

Microsoft 365 Copilot is the work / enterprise version of Microsoft Copilot — distinct from the consumer Copilot covered in the Microsoft Copilot entry. M365 Copilot is integrated directly inside:

Word — write / rewrite / summarise documents
Excel — analyse data, generate formulas, build pivot tables
PowerPoint — generate slides from prompts or Word docs
Outlook — summarise email threads, draft replies
Teams — meeting summaries, action items, chat-context AI
OneNote — note organisation and summarisation
OneDrive — file Q&A
Loop — collaborative AI work
Microsoft 365 Copilot Chat (the chat surface) — answers questions using your organisation’s data
Copilot Pages — AI-collaborated documents

The defining feature: Copilot uses YOUR organisation’s data (your emails, your team’s documents, your calendar, your SharePoint, your Teams chats — within permissions) as context for every response. Ask “what’s the status of project X” and Copilot can pull from emails, docs, meetings, and project files to give a real answer.

Critical privacy commitment: Microsoft 365 Copilot does NOT train on your data. This is contractually committed in the M365 Copilot terms. Your tenant’s data stays in your tenant; Copilot’s responses use your data only at the time of the request, never to update the underlying models.

What you’d use it for

Word

Draft / rewrite / summarise long documents
Generate from outline or talking points
Format / polish existing drafts
Translate

Excel

“Build a pivot table summarising sales by region”
“Find the trend in this data and chart it”
Generate formulas from descriptions
Data analysis

PowerPoint

“Generate slides from this Word doc”
“Make this presentation more visual”
Designer-style slide layout

Outlook

“Summarise this 47-message thread”
“Draft a polite decline to this meeting invitation”
“What are the action items from yesterday’s emails?”

Teams

“Catch me up on the meeting I missed”
“What action items came out of the project sync?”
Live transcription + speaker labels + action extraction

Cross-app

“Find me the latest proposal we sent to ClientX, and draft a follow-up email”
“What did Sarah ask me to do this week?”
“Schedule a meeting with everyone on Project Y to review Q3”

How to get it from Australia

Have an underlying M365 subscription — Microsoft 365 Business Basic / Standard / Premium, or Microsoft 365 E3 / E5 (Enterprise)
Add the M365 Copilot license — purchase via Microsoft 365 Admin Center → Billing → Add-ons
US$30/user/month, billed in AUD via Microsoft AUS billing
Annual commit required (no month-to-month for M365 Copilot specifically)
Once licensed, Copilot icons appear in Word / Excel / Outlook / Teams / etc.
For trial: Microsoft offers free trial periods for new customers; check current Microsoft 365 promotions

What it costs

M365 Copilot — US$30/user/month (annual)

Requires existing M365 Business / Enterprise subscription
Total cost: M365 subscription (US $10 - 22/ u ser / m o) + C o p i l o t (U S$ 30/user/mo) = US$40-52/user/mo
AUD billing native via Microsoft AUS — ATO-recognised tax invoice
Annual commit (no monthly billing for Copilot specifically)

M365 Copilot Chat (free with work accounts)

A free Copilot Chat surface for M365 work accounts
Does NOT include Word / Excel / PowerPoint deep integration
Uses publicly-available data, not tenant data
Good for evaluation before committing to full Copilot

Hidden costs to know about

Per-seat licensing model — can’t license selectively for specific Copilot features
M365 Copilot requires the underlying M365 license; total cost is meaningful
For very small businesses, consider whether per-seat cost justifies usage

How it compares to alternatives

Capability	M365 Copilot	Google Workspace + Gemini	Notion AI	Slack AI
Office suite integration	Best (Word / Excel / PowerPoint native)	Best (Docs / Sheets / Slides native)	Limited	Limited
Email integration	Outlook (best)	Gmail (excellent)	Limited	N/A
Meeting integration	Teams (excellent)	Meet (excellent)	Limited	N/A
Cross-app data context	Best (M365 ecosystem)	Best (Workspace ecosystem)	Limited	Limited
No-train commitment	Yes (contractual)	Yes (Workspace tier)	Yes	Yes
AUS data residency	Yes (Australia East)	Yes (Vertex AI Sydney)	Limited	Limited
Price per user / month	US $30 + M 365 (U S$ 10-22)	US$22-30 (Workspace + Gemini)	US $10 + N o t i o n (U S$ 10)	US$10/user (Slack AI add-on) + Slack
Best for	Microsoft Office shops	Google Workspace shops	Notion-centric teams	Slack-centric teams

For organisations already in M365 / Office workflows, M365 Copilot is the natural pick. For Google Workspace shops, Workspace + Gemini.

Gotchas

Don’t confuse with consumer Copilot. Microsoft 365 Copilot (work) ≠ Microsoft Copilot (consumer) ≠ Copilot Pro (personal Office) ≠ Copilot in Edge / Windows. All called “Copilot”; very different products.
Requires underlying M365 subscription — can’t buy M365 Copilot standalone. Total cost is M365 + Copilot.
Annual commit only — no monthly billing for Copilot specifically
Copilot’s data access respects M365 permissions — but if your org’s permissions are loose (shared with whole company), Copilot can surface things people didn’t realise was findable. Worth a permissions audit before rollout.
Excel Copilot quality is uneven — generates good summaries / pivots but advanced formula generation can have bugs; verify
PowerPoint slide generation is fine for first drafts but rarely production-ready
Outlook summarisation is excellent for long threads but can miss nuance
Teams meeting recap requires recording / transcript permissions — your IT department configures
Per-seat cost adds up — for a 50-person org, M365 Copilot is US$18,000/year just for Copilot
Initial value depends on adoption — orgs that train users see much better value than orgs that just buy licenses
For DIY power users, Copilot Pro (US$20/mo personal) gives Office Copilot features at home if you also have M365 Personal/Family
