Customize your agent

Customizing an agent goes beyond choosing colors and uploading a logo. It's how you establish identity, communicate purpose, and earn user trust—while staying consistent with the Copilot platform experience that users already know.

Microsoft 365 Copilot provides a structured framework for branding your agent. This framework defines where and how you can apply customization, balancing partner flexibility with a consistent Copilot experience. The result is a branded agent that feels recognizable and trustworthy without requiring custom layouts or complex design work.

Visual identity

Visual identity defines how an agent looks and is recognized at a glance. Elements such as the agent icon and accent colors help users immediately associate the agent with a trusted source.

By selecting a color theme, the agent reflects the visual identity of your organization or partner. It provides a consistent look and feel across experiences and helps users quickly recognize the agent within their workflow. Choose a primary color that represents the brand and ensure it meets accessibility contrast requirements.

The agent icon is an essential brand element that communicates identity at a glance. It helps users distinguish the agent from other tools and creates a familiar entry point for interaction. Upload an existing brand icon or create a simplified version that works at small sizes. Icons should follow brand guidelines, maintain visual clarity, and align with Microsoft design requirements for legibility and accessibility.

By keeping visual customization lightweight and structured, you can reinforce brand recognition without overwhelming the interface or compromising accessibility and contrast.

Presentation and messaging

Presentation and messaging shape how the agent introduces itself and communicates its purpose. Clear naming, short descriptions, and supporting text help users understand what the agent does and when it should be used. Providing this clarity early reduces uncertainty and helps users engage more confidently.

By aligning messaging with your voice and domain, agents feel more intentional and relevant. This alignment improves comprehension and leads to more effective interactions from the very first session.
