Explore the latest Microsoft 365 updates including Copilot enhancements, AI meeting recaps, Teams improvements, and new productivity features.

Copilot Cowork, an agentic system that can plan, execute, and complete work on a user’s behalf, is now generally available worldwide. Users can assign a task to Cowork, and it will work through the process from start to finish, returning a completed deliverable instead of a draft or recommendation.
Powered by Work IQ, Cowork uses organizational data and business context to help ensure tasks are completed using relevant information from connected systems. Administrators can monitor usage through the new Cost Management Dashboard in the Microsoft 365 admin center, which provides visibility into credit usage, budgets, and spending.

What will happen:

Smarter model selection in Copilot Cowork
Copilot Cowork can now automatically choose the most suitable AI model for a task. For example, it can use Anthropic models for visual work such as presentations and graphics, or GPT 5.5 for research tasks that require deeper analysis and citations. This helps users get the right capabilities for the job without having to select a model themselves.

Expanded plugin support in Copilot Cowork
Copilot Cowork now supports more plugins, allowing users to access additional business systems directly within their workflow. New plugins include Enosix, Harvey, LSEG, Miro, monday.com, Moodys, Morningstar, S&P Global Energy, and TeamsMaestro, with Databricks available through sideloading.
Support has also been added for Microsoft Fabric and the full Dynamics 365 portfolio, including Sales, Customer Service, and ERP applications.

Custom skills management in Copilot Cowork
Users can now create, edit, and manage custom skills directly from the Customize tab in Copilot Cowork. Skills are custom instructions that help Cowork work according to a user's preferred processes and requirements.
Users can build and refine skills over time, as well as combine their own workflows with partner-provided or organization-wide skills delivered through plugins. This makes it easier to standardize recurring tasks without having to rewrite the same prompts repeatedly.

Create visuals and branded presentations in Copilot Cowork
Copilot Cowork can now create and edit visuals such as presentation graphics, document illustrations, and email images directly within the workflow. This helps users generate visual content without switching between different tools.
Cowork can also use an organization's approved PowerPoint templates, including brand colors, fonts, logos, and layouts. This helps users create presentations that align with company branding from the start and reduces the need for manual formatting later.


Browser-based actions in Copilot Cowork
Copilot Cowork can now use the Edge browser to complete tasks across business systems, websites, and intranet sites. This allows Cowork to interact with information and tools across different web-based environments as part of completing a task.

Microsoft 365 Copilot continues to expand how it reasons over business data and provides more transparent answers. New capabilities bring Power BI and Dataverse data directly into Copilot experiences, while enhanced citations help users verify responses more easily.
