MMicrosoft Copilot Cowork

Copilot Cowork Turns Microsoft 365 Copilot Into a Task Runner

Copilot Cowork compared nearly 4,000 files across two product versions for one customer team, according to Microsoft, and turned a sales lead’s week of pipeline review into a single morning for another. Microsoft made Cowork generally available worldwide on June 16, 2026, after a three-month Frontier preview, and says more than half of the Fortune 500 already use it. Accenture, Capital Group, Koch and Zurich Insurance are among the names it lists.

Cowork takes a task, runs it across Microsoft 365 apps and connected tools in the cloud, and hands back a finished result. The price has two parts: a Microsoft 365 Copilot user license and a per-task charge in Copilot Credits, at $0.01 a credit on pay-as-you-go. That makes cost planning the main job for buyers. It scores 8.9 out of 10 on our scale, led by trust controls and autonomy.

Copilot Cowork From Frontier Preview to General Availability

We compiled the dated milestones and published terms. Each row links to the source.

The cost claim deserves a careful read. Microsoft compared its own Cowork with Anthropic’s Claude Cowork using the Microsoft 365 connector, on Opus 4.8, across 125 internal runs, and notes that actual costs may vary. It is a vendor test, but it shows Microsoft expects buyers to compare the two directly.

The grace period mattered for early adopters: tenants whose users tried Cowork during the preview were not charged before July 1, 2026. Anyone starting now pays from the first task, which is why the spending controls below are worth setting on day one.

Copilot Cowork Pricing in Licenses and Credits

Three Cowork Workloads Priced in Credits

We applied Microsoft’s per-task credit estimates to three teams. License costs come on top.

The pattern is clear. Capacity packs pay off when usage is steady and close to a multiple of 25,000 credits, as in the third case. When usage is uneven or falls just past a pack boundary, pay-as-you-go can cost less, as in the analyst case. Microsoft provides a downloadable estimator spreadsheet with task types and user personas, and running it on your own team mix before buying is the sensible first step.

Spending Limits, Data Controls and Model Choice in Cowork

• Off by default. Admins decide whether to enable Cowork and for whom.
• Spending limits. Set caps at tenant, group and user level, with custom alerts. Users can request more credits from inside Cowork.
• Reporting. Usage reports break down consumption by user, group and feature.
• Compliance. Audit log, DSPM, eDiscovery, Insider Risk Management, Data Lifecycle Management and Communication Compliance apply to Cowork. DLP is coming.
• Model cost. Heavier models cost more credits; the planned Cowork 1 model is aimed at lower cost.

How Copilot Cowork Runs a Task

Starting From the Copilot App

A toggle in the Microsoft 365 Copilot app opens the full Cowork experience. You describe the outcome you want, such as a reconciled spreadsheet, a comparison report or a pipeline summary.

Grounding in Work Data

Cowork uses Work IQ to ground the task in your business data, from files and mail to meetings, all inside the Microsoft 365 trust boundary. Sensitivity labels on source files carry through to its output.

Running in the Cloud

Tasks run in the cloud, so files are not stored locally and the work continues if you close your laptop. This is what allows long jobs, such as reading thousands of files, without tying up a machine.

Using Tools and Plugins

Cowork can call several tools in one task. Plugins add outside data and actions: Enosix, Harvey, LSEG, Miro, monday.com, Moody’s, Morningstar, S&P Global Energy and TeamsMaestro are live, with Adobe, Atlassian, Box, Canva, CB Insights, Databricks, MoneyForward and Templafy coming. Fabric and Dynamics 365 Sales, Customer Service and ERP apps are generally available. In Frontier, Cowork can also browse the web through a local Edge browser under your enterprise policies.

Choosing the Model

Users can pick a model per task. At launch Cowork runs on Anthropic models including Opus 4.8 and Sonnet 4.6. Model choice is one of the four inputs to task cost, so a lighter model is a direct way to spend fewer credits.

Returning the Result

Cowork hands back a completed result. Each task shows its cost in credits, so users see what their work used.

A Finance Analyst’s Cowork Task, Step by Step

This example uses the capabilities Microsoft documents to show how one medium task might run.

• The request. An analyst asks Cowork to compare this quarter’s vendor spend workbook with last quarter’s, flag every vendor whose spend rose more than 20 percent and draft a summary for the CFO.
• Grounding. Cowork finds both workbooks and the related email threads through Work IQ. The workbooks carry a Confidential label, which stays on the output.
• The work. It runs the comparison across tabs, builds a list of flagged vendors and pulls context from the email threads about any new contracts.
• The analyst steps away. The task runs in the cloud while the analyst joins a meeting with the laptop closed.
• The result. Cowork returns the flagged list and a draft summary, with the task cost shown in credits.

At Microsoft’s medium-task estimate of 400 to 700 credits, this job would cost $4 to $7 at pay-as-you-go rates. The analyst still reviews the list before it reaches the CFO, which is where the accuracy complaints in Copilot reviews are caught.

What Microsoft’s Customer Examples Suggest

Microsoft shared three short examples at general availability: an engineering team that automated batch-job spreadsheet edits, a team that compared nearly 4,000 files across two product versions, and a sales lead who turned a week of pipeline review into one morning. None comes with a cost figure, but all three share a shape. Each is a repetitive job across many files, with a clear finished output.

That shape is a good filter for your own pilot. Tasks with many inputs and a checkable result, such as reconciliations, version comparisons and status reports, suit Cowork. Open-ended thinking work, such as strategy writing, is better done with regular Copilot chat, where each turn is cheaper and you steer as you go.

Setting Up a Copilot Cowork Pilot

Because Cowork is off by default and billed per task, a short pilot with clear limits takes little setup.

• Pick a group. Enable Cowork for 10 to 20 licensed users with repetitive multi-file work.
• Set caps. Put a monthly credit limit on the pilot group and alerts at 50 and 80 percent.
• Choose tasks. Agree on three recurring tasks per team and note how long they take today.
• Estimate first. Run Microsoft’s estimator spreadsheet for those tasks before switching on.
• Review weekly. Use the usage reports by user and feature, and compare credits spent with hours saved.

After a month you will know your real credits per task and whether a capacity pack or a P3 commitment beats pay-as-you-go.

Copilot Cowork Compared With Claude Cowork, Gemini Enterprise and Rovo

For a company standardized on Microsoft 365 with strict compliance needs, Cowork keeps the work inside existing labels, audit logs and eDiscovery. Claude Cowork offers a simpler subscription for smaller teams. Gemini Enterprise is the parallel choice for Google Workspace shops. See our productivity agents page for more.

Teams That Get the Most From Copilot Cowork

Analysts and operations staff with long, repetitive jobs across many files are the clearest fit: comparing versions, editing batches of spreadsheets and building reports from mail and documents. Sales leaders reviewing pipeline across CRM data and email also fit, given Microsoft’s example.

Large enterprises already paying for Copilot licenses across the company gain the most from the shared credit model. A central IT team can buy capacity once, set caps per department and watch usage reports, which suits organizations that charge AI costs back to business units.

Regulated firms in finance, insurance and legal services gain from the compliance tooling and from plugins such as LSEG, Moody’s, Morningstar and Harvey. Microsoft names Zurich Insurance and Capital Group among users.

Organizations That May Want to Wait on Cowork

Teams without Microsoft 365 Copilot licenses face the license cost before the first task, which is a lot for occasional use. Organizations that need data loss prevention enforced on agent output may want to wait until DLP support arrives, since Microsoft lists it as coming soon.

Teams whose work lives mostly outside Microsoft 365, such as in Google Workspace or a specialist industry system without a plugin, will get less from Cowork’s grounding in Work IQ. The plugin list is growing, so check whether your main tools are on it.

Finance teams that need predictable monthly bills may also prefer to start with a small pilot group, since usage-based credits vary with model, context, tools and runtime.

What G2 Reviewers Say About Microsoft Copilot

Microsoft Copilot holds 4.3 out of 5 from 655 G2 reviews, with 429 five-star, 182 four-star, 32 three-star, 9 two-star and 3 one-star ratings, so more than 90 percent of reviewers give four or five stars. Reviewers praise how it works with Word, Excel and Outlook, the time it saves on emails and summaries, and quick access through Edge and Windows. Complaints include generic or inaccurate answers that need checking, slow handling of large documents and spreadsheets, and dependence on prompt wording. These reviews cover Copilot broadly; Cowork is newer and built for longer tasks, so test it on your own files.

How Copilot Cowork Rates on Our Scale

Copilot Cowork scores 8.9 out of 10 on our scale. Trust and security is its highest criterion, since it inherits Microsoft 365 compliance tools and adds spending controls. Autonomy and integrations are high too, with end-to-end cloud tasks and a growing plugin list. Pricing value is lower because of the two-part cost and variable per-task usage.

For a Microsoft 365 Copilot customer, a one-month pilot with 10 to 20 users and a firm spending cap is the right way in. Compare credits used against hours saved on two or three recurring tasks, then decide between pay-as-you-go and capacity packs.
