Microsoft 365 Copilot operates within enterprise governance and compliance controls. For conversation history, tenant administrators can configure retention and deletion policies. Therefore, users can delete conversation history only if allowed by administrative policy, making Statement 1 correct.

Deleting a Copilot conversation removes the chat interaction but does not delete underlying source files such as documents stored in SharePoint or OneDrive. These files are governed independently by Microsoft 365 storage and retention policies. Hence, Statement 2 is incorrect.

When a Copilot agent is uninstalled, it removes access to the agent interface but does not delete previously generated conversations. Conversations are stored as part of user activity history and remain available unless explicitly deleted (subject to policy). Therefore, Statement 3 is correct.

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

Prompt-grounding means ensuring Copilot’s response is based on authoritative, relevant source material rather than inferred or generalized information. Microsoft guidance for Copilot emphasizes that the most effective way to ground responses is to explicitly point Copilot to the content you want it to use—such as specific SharePoint documents, OneDrive files, emails, meeting notes, or other Microsoft 365 resources the user has permission to access.

Option D is therefore the best answer because referencing specific files anchors Copilot’s reasoning to the exact material that should be used for facts, terminology, and details. This reduces hallucinations (fabrication) and improves accuracy and traceability, especially when Copilot can provide citations back to the referenced sources.

Option B (desired output format) improves structure and readability but does not, by itself, ground content. Option A can sometimes improve clarity, but shorter prompts do not guarantee grounding. Option C may help comprehension in some cases, but it is not a grounding strategy and can be counterproductive if the source material is technical.

Therefore, the best approach to improve prompt-grounding is to reference specific files .

Copilot in Microsoft Teams is designed to help users work faster by summarizing meeting content and assisting with message composition in chats and channels. Microsoft guidance highlights that Copilot can synthesize what was discussed in a meeting by generating a structured recap that includes key points, decisions, and action items. This directly matches option C . Copilot can also help you respond more quickly in Teams conversations by drafting replies grounded in the context of the existing chat or channel thread, which matches option D .

Options A and B are not Copilot capabilities. Muting and unmuting participants is a meeting control function handled by Teams meeting roles and settings, and it is not automatically driven by Copilot based on participant location. Creating custom backgrounds is a Teams visual feature (and can involve Designer or image tools), but it is not a Copilot-in-Teams productivity function for summarization or drafting based on conversation context.

Therefore, the two tasks you can achieve using Copilot in Teams are generating meeting summaries with decisions and action items, and drafting responses to channel messages based on conversation context.

Microsoft provides centralized activity management controls through the My Account portal, which allows users to manage privacy settings, activity history, and data associated with Microsoft 365 services, including Copilot. When the requirement is to delete all conversations with minimal effort, the most efficient method is to use the account-level activity management tools rather than deleting conversations individually.

The My Account portal enables bulk management of Copilot activity data, allowing users to clear conversation history in a consolidated manner. This approach aligns with Microsoft’s privacy-by-design framework, giving users control over their AI-generated interaction history without requiring administrative intervention.

Using the Copilot web or desktop app would typically require manually deleting conversations one at a time, increasing effort. The Windows 11 Settings app is unrelated to Microsoft 365 Copilot data management.

Therefore, to delete all Copilot conversations efficiently and with the least amount of effort, the correct approach is to use the My Account portal in Microsoft 365.
