Delete Only Selected Conversations

If you don’t want to remove everything, you can delete specific chats:

1. Open Copilot (app or browser).
2. Find the conversation you want to remove.
3. Hover over it or tap the options (three dots).
4. Click Delete.
5. Confirm your choice.

Only that conversation will be deleted, and the rest will stay saved. This option is helpful when you want to keep important chats but remove unnecessary ones.

Why You Should Delete Copilot Chat History

Copilot works across many Microsoft 365 tools, and your activity can appear in different places. Old chats might show up during screen sharing, meetings, or presentations.

For example:

• Practice prompts may appear during live demos
• Personal queries could be visible during screen sharing
• Old data might create confusion in meetings

Deleting your history helps avoid these situations and keeps your information private.

Apps Where Copilot Activity Is Stored

Copilot is integrated into several Microsoft 365 apps, including:

• Word (documents)
• Excel (data and spreadsheets)
• PowerPoint (presentations)
• Teams (meetings and chats)
• Loop (collaboration)
• Planner (task management)
• Whiteboard (visual brainstorming)
• Forms (surveys and feedback)

Your activity can be saved across these apps, so clearing history removes data from the entire system.

Delete Copilot History Across Microsoft 365

To remove activity from all connected apps, follow these steps:

1. Open the Microsoft 365 website.
2. Click your profile icon (top right).
3. Select View Account.
4. Go to Settings and Privacy.
5. Open the Privacy section.
6. Find Copilot Activity History.
7. Click Delete History.
8. Select the activity type (Microsoft 365 Copilot).
9. Confirm by clicking Delete.

This will remove your Copilot data across all Microsoft 365 services.

How Long Does It Take?

In most cases, the deletion process is quick and completes within a few seconds. However, it may take up to 10–15 minutes in some situations.

Once the process is finished, your old chats will no longer be visible.
