Copilot Cowork: the usage-billed Microsoft 365 AI agent launches everywhere

On June 16, 2026, Microsoft made Copilot Cowork available worldwide. Behind the slightly technical name sits a meaningful shift in how artificial intelligence works inside Microsoft 365: instead of helping you write a draft, Cowork takes a whole task, carries it from start to finish, and hands you the finished result. It keeps working even when your computer is off, because everything runs in the cloud.

For a small business in Trois-Rivières, the Mauricie or anywhere else in Quebec, the real news is not only a new AI agent. It is the new way it is billed: no longer a fixed monthly amount, but payment based on what you consume. That opens possibilities, and it also calls for watching the invoice closely. Here is what changes, in plain terms.

1. What is Copilot Cowork?

The Copilot most people know waits for a question, then answers. Cowork goes further. It is what people call an agent: you hand it a goal and it works through the steps itself to reach it. According to Microsoft, it can combine several tools and several data sources in your Microsoft 365 environment (Teams, Outlook, SharePoint, your files) to produce a complete deliverable, not just a starting point.

In practice, that means tasks such as:

• Preparing a detailed report by pulling information from several documents and mailboxes.
• Following up on a file over several days without you having to restart it.
• Working through a long run of repetitive steps while you do something else.

The key point: the work happens in Microsoft’s cloud, inside the security and compliance rules already in place in your Microsoft 365. Your workstation can be off and the task keeps going.

2. The real change: you pay for what you use

This is where the business model shifts. Cowork does not run on a fixed per-user price. You first need a Microsoft 365 Copilot licence (the USL), and then Cowork usage is billed in Copilot credits, based on what you actually consume.

Microsoft offers two payment options: pay-as-you-go (the credit is quoted at around 0.01 US dollars for reference, with the current official price at Microsoft), or commit to a volume in advance for a discount. The cost of a task depends on four factors: the AI model used, the amount of information to retrieve, the number of tools called and how long the task runs.

To give a sense of scale, Microsoft sorts tasks into three categories (indicative figures, to be confirmed at the source):

• Light task: a quick summary, roughly 100 to 300 credits.
• Medium task: roughly 400 to 700 credits.
• Heavy task: a large report with several outputs, 700 credits and up.

The logic resembles an electricity bill: the bigger and longer the task, the more it costs. That is flexible, but it means keeping an eye on consumption, exactly as you would for any cloud service. Our managed IT services team helps small businesses frame this kind of variable spending before it gets away from them.

3. Why does this matter for your business in Quebec?

Many companies in the region already pay for Microsoft 365 subscriptions. Cowork adds a useful layer of automation, and a new cost line to understand. Here is what changes in practice:

• Time recovered. Long, tedious tasks (compiling, sorting, following up) can be handed off, freeing your employees for higher-value work.
• Spending to watch. The usage model is advantageous when governed, risky when left open with no limit. An employee could launch several large tasks without realizing the cost.
• A decision to make. Should you enable it for everyone, for a pilot team, or not at all for now? The right answer depends on your real needs.

According to Microsoft’s own testing, Cowork is on average 30 to 40 percent cheaper than the equivalent Claude agent connected to Microsoft 365. That figure comes from Microsoft, so take it as an indication rather than gospel, but it shows the cost battle between AI agents is real.

4. The guardrails: off by default and controlled by an administrator

Good news: Cowork is off by default. Nothing runs and nothing gets billed until an administrator deliberately turns it on in your environment. Microsoft also built a cost management dashboard into the Microsoft 365 admin centre so you keep control.

Among the tools available to prevent overruns:

• Spending caps set by organization, by group or by user. When the limit is reached, billing stops.
• Alerts that notify the people in charge as soon as a threshold you set is passed.
• Logs and reports to see who is consuming what and understand the costs.

Worth noting as well: customers who took part in the preview program (from March to June 16) get a grace period and are not billed for Cowork before July 1, 2026. If your organization was in that group, now is the moment to set your limits before billing starts. Unsure where you stand? Contact our team and we can check your tenant with you.

5. What we recommend at OKTO

Agent-based automation is a genuine advance, but the usage model calls for discipline. Before enabling Cowork across the whole company, we recommend starting small: a pilot group, clear caps, alerts in place, and a review of consumption after a few weeks. That is the best way to capture the time savings without a surprise invoice.

This is exactly the kind of support OKTO Solutions provides to small businesses in Trois-Rivières and the Mauricie: configuring the right guardrails, explaining to teams what each task costs, and keeping your Microsoft 365 environment secure while you explore these new tools.

Frequently asked questions

Is Copilot Cowork included in my Microsoft 365 subscription?

No. Cowork requires a Microsoft 365 Copilot licence, and usage is then billed separately, in credits, based on what you consume. It is not a fixed amount included in the base subscription.

Will Cowork turn itself on and generate costs?

No. It is off by default. An administrator has to deliberately enable it, and can set spending caps by organization, by group or by user to keep control.

How much does a task cost in Cowork?

It depends on the task. Microsoft gives indicative ranges, from roughly 100 to 300 credits for a light task up to more than 700 credits for a heavy one. The exact cost varies with the model, the amount of information processed and the processing time. Always check Microsoft’s official pricing, which can change.
