Microsoft Copilot is shifting from answering questions to doing the work. Here's what Copilot Cowork is, how it's different, and how to adopt it without handing an AI the keys.
Most people know Copilot as the assistant inside Word, Outlook and Teams that drafts and summarises. Copilot Cowork is the next step — and it's a genuine change in how the tool works. Instead of helping you with one thing at a time, you give it an outcome and it carries out the whole job across your apps.
Copilot Cowork — from answering to doing
The next step for Microsoft 365 Copilot: you describe the outcome, and Cowork plans the work and carries it out across your apps — drafting, analysing and scheduling — then pauses for your approval. We help you switch it on safely.
Built on Anthropic's agentic technology, running inside your Microsoft 365 tenant under your existing controls. Cowork is rolling out through Microsoft's Frontier early-access program — we help you adopt it with the right licensing, permissions and approval workflow. Illustrative example.
How is Cowork different from today's Copilot?
Microsoft Copilot Cowork is the agentic side of Microsoft 365 Copilot: you hand it an outcome, and it plans the steps and carries them out across Outlook, Teams, Word, Excel and PowerPoint, asking your permission before it acts. Key IT helps Melbourne businesses get Microsoft 365 ready for it and switch it on safely.
With everyday Copilot you ask and it answers — a draft email, a meeting summary, a formula. Cowork works through the whole job instead, reading across your files and mailbox, building documents, crunching numbers, booking meetings and lining up messages while it shows each step. Microsoft puts a Cowork task at minutes to hours, against seconds to minutes for Copilot Chat. The shift is from a clever assistant to a Copilot agent that takes multi-step work off your plate.
What can Copilot Cowork actually do?
According to Microsoft, Cowork can create documents, draft and send emails, schedule meetings, post in Teams and manage your calendar. Recent updates go further: editing existing Word, Excel and PowerPoint files in OneDrive and SharePoint, completing web tasks in Microsoft Edge, and running automations on a schedule or when a matching email or Teams message arrives. You can pause or steer it at any point and — importantly — it asks for your approval before it sends, posts or books anything. So an agent might prepare a client review pack end to end, but nothing leaves your business until you say go.
Is Copilot Cowork built on Claude, and where does your data go?
Yes, Cowork is built with Anthropic: Microsoft brought the technology that powers Claude Cowork into Microsoft 365 Copilot, and its model picker offers Claude models alongside OpenAI's GPT models, or lets Cowork choose. Your files are processed in a temporary, isolated workspace inside the Microsoft 365 service boundary, and the agent only sees what the signed-in user can already open. Anthropic works as a Microsoft subprocessor, so Microsoft's data protection terms apply. The exception is any model flagged "with data retention", which stays off until an admin deliberately opts in.
Is Copilot Cowork available in Australia yet?
Yes. Microsoft 365 Copilot Cowork moved from a limited research preview into Microsoft's Frontier early-access program in late March 2026, gained plugins in April and a mobile app in May, then became generally available to Microsoft 365 Copilot tenants worldwide in June 2026, Australian businesses included. It still isn't automatic: each user needs a Microsoft 365 Copilot licence, and an admin has to switch on usage-based billing (Copilot Credits) with a spending policy that covers Cowork. Microsoft keeps adding to it — our August 2026 Copilot update covers the newer workflow features. It's here and moving fast, but adopting it is a decision, not an accident.
What are the risks of Copilot Cowork?
The main risk is reach. An assistant that suggests things is low-risk; an agent that acts — sends emails, posts in Teams, books meetings — uses every permission its user has, including over-shared folders nobody remembers, so it needs guard rails. The same things that make Copilot safe make Cowork safe: clean Microsoft 365 permissions so it can only touch what it should, a clear approval workflow so a human signs off, and sensible AI governance. Watch the shortcuts too: the approval prompt offers "Always allow" for similar actions in the same conversation, and automated tasks can be pre-approved when they're set up, so staff need to know where a human sign-off is non-negotiable. Get those right and Cowork gives your team time back, with a sanctioned alternative to shadow AI. Skip them and you've handed an automated agent broad reach into a messy environment.
Should your business adopt Copilot Cowork yet?
If you already run on Microsoft 365 with reasonable data hygiene, yes — start now, in stages. If your permissions are loose or undocumented, sort that first; a cybersecurity health check will show you exactly where you stand. Still deciding whether Copilot pays its way at all? Read is Microsoft Copilot worth it first. A sensible Cowork rollout looks like this:
Licences and spend
Decide who gets a Copilot licence, then set a Cowork spending policy with per-user or per-group limits so usage costs can't drift.
Permissions
Clear out broad "Anyone" links and "Everyone" access, and tighten over-shared SharePoint sites and Teams, because the agent can reach anything its user can.
Approval rules
Agree where a person must always sign off — payments, client emails, anything leaving the business — and when "Always allow" is acceptable.
A small pilot
Start with one team and one repeatable job, such as a weekly report pack or meeting prep, measure the hours saved, then widen.
The audit trail
Cowork activity is recorded in the Microsoft 365 unified audit log, so review what it actually did in the first few weeks.

Frequently asked questions
What is Microsoft Copilot Cowork?
Copilot Cowork is the agentic mode of Microsoft 365 Copilot, built with Anthropic. Rather than answering one prompt, it takes a goal, plans the steps and completes them across Outlook, Teams, Word, Excel and PowerPoint, checking with you before it sends, posts or schedules anything.
How is Cowork different from regular Copilot?
Regular Copilot answers and assists one request at a time inside an app. Cowork takes an outcome and works through the whole job across your Microsoft 365 apps, with visible progress and your sign-off on each action.
Is Copilot Cowork available now?
Yes. After a Frontier early-access phase from late March 2026, Microsoft made Cowork generally available to every Microsoft 365 Copilot tenant worldwide in June 2026. Each user still needs a Copilot licence, and an admin must enable usage-based billing before anyone can use it.
Is it safe — who's in control?
You are. By default Cowork waits for your go-ahead before sending, posting or scheduling, works only with data each user can already open, and logs its activity for your admins. The thing to fix first is permissions: if a folder is over-shared, the agent can reach it too.
How much does Copilot Cowork cost?
Cowork sits on top of a per-user Microsoft 365 Copilot licence and is billed by usage: tasks consume Copilot Credits, and the more a task does, the more it uses. Admins see usage in the Microsoft 365 admin center and can cap it per user or group. We can help you estimate usage and set those limits before rollout.
