Microsoft Copilot for Business.

Microsoft 365 Copilot Chat is the simplest way to start using generative AI in a business environment. For users with eligible Microsoft 365 plans, the basic web-grounded chat experience is available at no additional cost.

The main limitation concerns access to organizational data. The basic Copilot Chat experience does not automatically have full access to the user’s work context from emails, meetings, documents, and other Microsoft 365 resources. Access to chat grounded in work data depends on the appropriate Copilot license and the user’s existing permissions.

Copilot Chat also allows users to create simpler agents with Agent Builder. Agents based on instructions and public sources can operate without additional charges, while scenarios that use shared organizational data may require usage-based billing through Copilot Credits or a pay-as-you-go model.

If you expect Copilot to work not only with the web or a single file, but also with your organization’s context, Microsoft 365 Copilot is worth considering.

The solution is integrated with applications such as Word, Excel, PowerPoint, Outlook, and Teams. It uses Microsoft Graph and Work IQ – an intelligence layer that connects the user’s current work context with information available across the Microsoft 365 environment.

Microsoft also provides specialized agent capabilities, including tools designed for more complex research and analytical tasks, such as Researcher and Analyst.

What about data security?

This is one of the most important considerations when implementing AI in an organization. Microsoft 365 Copilot respects the user’s existing permissions: it can use organizational data that the user is authorized to access, but it should not expose content outside that scope. Prompts, responses, and data retrieved through Microsoft Graph are not used to train the underlying foundation models.

Before deploying Copilot, it is therefore worth reviewing and organizing access permissions in SharePoint, Teams, and other data sources. AI will not fix excessive or incorrectly configured permissions. However, it can make existing issues more visible because users may be able to find information they already had access to much faster.

Microsoft 365 Copilot supports the user’s day-to-day work. Copilot Studio takes this a step further by allowing organizations to build specialized AI agents that perform specific tasks or business processes.

An agent can use selected data sources such as SharePoint, Dataverse, APIs, or other business systems. It can not only provide an answer, but also perform a specific action – for example, create a record, send a notification, or trigger a process.

Depending on the scenario, the agent can be made available in Microsoft 365, Teams, a business application, or supported external channels.

How does Copilot Studio licensing work?

There is no single licensing model that fits every implementation. Copilot Credits are the common billing unit for Copilot Studio capabilities. An organization can use prepaid capacity or a pay-as-you-go model, where charges are based on actual usage.

The cost therefore depends not only on building the agent itself, but also on the number of users, the type of interactions, the actions performed, and the data sources used. That is why the cost model should be estimated before deployment, rather than only after the solution has been rolled out at a larger scale.

If your organization employs developers, GitHub Copilot should be treated as a separate category of solution. It is not the equivalent of Microsoft 365 Copilot for office workers, but an AI assistant designed primarily for software development and maintenance.

Business and Enterprise plans are available for organizations, providing centralized management of access, policies, and usage. Under the current model, some advanced usage is billed through GitHub AI Credits, so larger teams should monitor not only the number of assigned seats, but also the actual use of AI features.

While Copilot Chat supports everyday tasks related to information and content, Copilot in Power BI is designed for working with data, semantic models, and reports. It can support both analysts and BI developers, as well as business users working with existing reports.

Requirements and data security

To use Copilot in Power BI, the organization needs appropriately configured paid capacity. Supported options currently include paid Microsoft Fabric capacities starting from F2 and Power BI Premium starting from P1. Microsoft also offers a Fabric Copilot capacity model, which allows Copilot usage to be billed separately from some analytical workloads.

Access to Copilot does not replace the standard licensing and access requirements for Power BI. Users still need the appropriate permissions for workspaces, reports, and data according to the organization’s access model.

From a security perspective, Copilot respects existing data roles and permissions. This includes mechanisms such as Row-Level Security and information protection features such as sensitivity labels.

Microsoft Fabric is a comprehensive cloud analytics platform that brings together data integration, Data Engineering, data warehousing, Data Science, real-time analytics, and Power BI in a single environment. Copilot in Fabric supports specialists working across different stages of the data lifecycle.

Access to Copilot in Microsoft Fabric requires appropriate paid capacity and tenant configuration. Depending on the model, an organization can use Fabric/Premium capacity or Fabric Copilot capacity. Usage is billed at the capacity level, allowing AI capabilities to be shared across teams working on common projects without designing a separate licensing model for every individual operation.

It is also important to remember that Copilot capabilities vary across individual Fabric workloads, and some features may be available in Preview. Before implementing a specific scenario, organizations should therefore verify its current availability in the region and configuration they use.

The simplest way to think about these solutions is:

Microsoft 365 Copilot Chat – when you need secure AI for everyday, basic tasks.

Microsoft 365 Copilot – when AI needs to work with the context of documents, emails, meetings, and Microsoft 365 applications.

Microsoft Copilot Studio – when you want to build a specialized agent that supports a specific business process.

GitHub Copilot – when you want to support developers and IT teams in software development.

Copilot w Power BI – when you want to speed up report creation, data analysis, and the preparation of business insights.

Copilot w Microsoft Fabric – when you want to support data teams with integration, processing, data engineering, and Data Science.

In larger organizations, the answer is often not to choose a single Copilot. The best results may come from combining several solutions for different user groups and processes – provided that each one has a clearly defined purpose.

The most common mistake when implementing AI is purchasing licenses without first defining where Copilot is expected to deliver business value. Simply making the tool available does not mean users will use it in a way that saves time or improves process quality.

Before deployment, it is worth:

selecting specific business scenarios,

reviewing data quality and permissions,

identifying which user groups actually need the full Copilot experience,

running a pilot,

monitoring license and AI feature usage,

measuring time savings and the impact on the process,

scaling the solution only after that.

This way, Copilot does not become just another tool “purchased for the entire company,” but a real part of process transformation – implemented where a specific business outcome can be identified.
