You are creating an agent in the Microsoft 365 Copilot app.

Microsoft 365 Copilot agents are designed to integrate with Microsoft 365 data sources and provide flexible, natural-language-driven configuration. Agents can be connected to organizational data such as SharePoint, OneDrive, and Exchange. Since shared mailboxes are part of Exchange Online and accessible through Microsoft Graph (subject to permissions), agents can be configured to search shared mailboxes, making Statement 1 correct.

Microsoft also enables natural language creation of agents , allowing users to describe what the agent should do, its purpose, and behavior using conversational instructions rather than requiring code. This simplifies agent creation and aligns with Copilot’s low-code/no-code approach, so Statement 2 is correct.

However, agents cannot use other agents as knowledge sources. Knowledge sources are limited to structured content such as files, sites, and data repositories. Agents operate independently rather than being nested or chained as data sources, making Statement 3 incorrect.

Thus, the correct answers are Yes, Yes, No .
