Microsoft 365 Copilot may already be helping you draft emails, summarise meetings and find information faster. Copilot Cowork takes that assistance further. Instead of using AI for one prompt at a time, you can use Cowork to coordinate work across multiple steps, applications and sources of information.
Now readily available to Microsoft 365 Copilot customers, Cowork can help employees complete more complex work, improve efficiency and increase output. However, businesses need to consider two areas before enabling it: security, as broader AI access to business data can amplify existing permission and governance gaps, and budget, as Cowork tasks incur usage-based charges through Copilot Credits in addition to the Microsoft 365 Copilot licence.
In this article, we explain how Copilot Cowork works, how it differs from Microsoft 365 Copilot and what your business should consider before getting started.
What is Microsoft Copilot Cowork?
Copilot Cowork is designed to help people complete complex work more efficiently. It is an agentic capability within Microsoft 365 that can plan and carry out multi-step tasks with your direction.
You describe the outcome you need and provide relevant context, including how you would approach the task. The more specific your instructions, the better Cowork can develop an appropriate plan and select the right tools. Powered by Work IQ, Microsoft’s context engine, it can draw on emails, meetings, messages, files and business data, so the work reflects your organisation’s context. For example, you could ask it to prepare a meeting brief and supporting presentation as one connected task.
That does not mean handing over control. You remain involved throughout the process. You can review Cowork’s approach, follow its progress and provide further direction. Users can also or pause, resume or cancel the task at any time. It also pauses for approval before consequential actions, such as sending an email, scheduling a meeting or updating a record.
How is Cowork Different from Microsoft 365 Copilot?
The key difference between Microsoft 365 Copilot and Cowork is the scope of work they can handle. Copilot assists with individual activities, while Cowork supports more complex tasks involving multiple steps. In practical terms, Cowork is the next level of AI assistance within Microsoft 365.
Copilot helps with individual tasks in the flow of work, such as drafting an email in Outlook, summarising a Teams meeting or analysing information in Excel. You provide the prompt, review the response and guide what happens next.
With Cowork, you set the task and review the result, while it handles the work in between. Because it runs in the cloud, tasks can continue when your laptop is closed. They can also run at a scheduled time or be triggered by an event, such as when an email arrives.
The two serve different purposes. Copilot remains useful for quick answers, drafts and individual actions, while Cowork is suited to work that needs to move beyond a single prompt.
What Can Businesses Use Copilot Cowork For?
Some tasks take hours simply because they involve gathering information, moving between apps and producing multiple outputs. In its Cowork announcement, Microsoft shared several examples of how the tool can support everyday work across Microsoft 365:
- Struggling to get on top of a busy calendar and protect focus time?Cowork can review your upcoming meetings, flag conflicts and propose changes. Once approved, it can reschedule or decline meetings and add focus blocks.
- Spending hours preparing for customer meetings?Cowork can gather relevant emails, files and meeting information, then turn them into a briefing document, supporting analysis and a presentation.
- Need to research a company quickly?Cowork can bring together relevant information from work and web sources, then package the findings into an executive summary, detailed report and spreadsheet.
- Coordinating a launch across multiple apps?Cowork can research competitors, develop the launch plan and create supporting materials across Word, Excel and PowerPoint.
With the right connectors and plugins, Cowork can also extend into other systems used across your business.
How Does Cowork Connect to Other Business Systems?
Through Microsoft 365 Copilot connectors and plugins, Cowork can extend beyond Microsoft 365 and draw on relevant information from other business systems to deliver more complete and informed results. Depending on the systems connected, this could support:
- Sales systems and CRMs: Review account and opportunity information, identify stalled deals and prepare tailored follow-up communications.
- Service desk platforms: Bring together ticket details, emails and Teams conversations to produce incident summaries and stakeholder updates.
- Project management tools: Combine project statuses, deadlines and recent communications into a weekly operations report.
- Finance and ERP systems: Draw on approved financial information to identify key movements and prepare structured reports for leadership.
Is Copilot Cowork Secure?
Copilot Cowork operates within Microsoft 365’s existing security, privacy and compliance environment. Your organisation’s identity controls, user permissions and policies continue to apply, and Cowork can only access information the user is already authorised to see. Its actions and outputs are auditable, while sensitivity labels carry through to generated content.
Cowork also pauses before consequential actions, such as sending an email, posting in Teams or updating a record, allowing users to review each action before it is completed.
However, these protections do not replace good data governance. Businesses should review user permissions, information access and any connectors or plugins before enabling Cowork.
If your business needs support reviewing these areas, Ever Nimble’s AI security services can help identify potential gaps and prepare your environment for a secure rollout.
What Should Your Business Consider Before Getting Started?
Getting value from Cowork requires more than enabling access. Businesses need clear use cases, appropriate controls, training and a plan for measuring its value.
Before getting started:
- Choose the right use cases: Focus on repetitive, time-consuming tasks involving several steps or outputs. Start where the potential time saving is easy to identify.
- Decide who needs access: Cowork may be more valuable to some roles than others. Prioritise users with suitable tasks rather than enabling it across the business immediately.
- Understand the costs: Cowork requires a Microsoft 365 Copilot licence, with usage billed separately through Copilot Credits. Set budgets and usage alerts before access expands.
- Prepare your users: Provide practical AI training so employees can give clear instructions, review outputs carefully and understand when approval is required.
- Start with a pilot: Test Cowork with a small group, monitor usage and compare the time saved with the cost before rolling it out more widely.
A measured rollout will help your business identify where Cowork delivers genuine value while keeping security, usage and costs under control.
