How do I turn off Copilot personalization based on chat history?

Copilot Memory​​​​​​​ automatically collects key details from your previous chat conversations and remembers it for future conversations.

If you don’t want Copilot Memory to use your previous chats to respond to future prompts, complete the following steps:

  1. Go to Copilot Chat and sign in with your Microsoft 365 work or school account.

  2. At the top right of Copilot Chat, select ... Copilot chats and more and select  Machine cogs to access Copilot settings Settings from the menu.

  3. In the Chat settings window, select  People with machine cogs for Copilot personalization settings Personalization from the left-side menu.

  4. In the Chat history tile, move the toggle to the Off position.

Caution: 

  • Turning off Chat history personalization deletes any inferences Copilot made from previous chats.

  • This data is removed from the Copilot system after 30 days, ensuring your privacy and control over what’s remembered.

  • If the toggle is turned on within the 30-day grace period, Copilot overrides the deletion so that conversation data isn’t lost.

How does Copilot use my chat history?

Copilot may use context from previous chat conversations to improve future responses by making inferences about what is important to remember. For example, if you once mentioned you’re planning a business trip to Japan, it might suggest travel tips when you ask, “What should I pack?

Copilot doesn’t remember every detail from your previous chats, only what’s useful for personalizing its responses to your questions and tasks.

If there’s a chat conversation you don’t want Copilot to reference, you should delete that conversation.
