M365 Changelog: Chat history coming to Microsoft Copilot with commercial data protection (formerly Bing Chat Enterprise) – ON HOLD


The rollout of chat history for Microsoft Copilot with commercial data protection is on hold. It allows users to view and continue past chats. A PowerShell script is available to manage this feature, which will be rolled out in mid to late May 2024. Users must consent to new terms to use chat history, which is stored for 30 days.

MC789319 – Chat history will be turned on for Microsoft Copilot users with commercial data protection (formerly Bing Chat Enterprise). Chat history lets users return to a previous chat and view prompts and responses. Users can also continue the chat.

To disable or enable chat history prior to the feature update being rolled out, or to manage it after rollout, a PowerShell script is available.

This message is associated with Microsoft 365 Roadmap ID 392873

When this will happen:

General Availability: Microsoft will begin rolling out mid-May 2024 and expects to complete by late May 2024. 

How this will affect your organization:

If chat history is enabled, user chat data will be saved within your organization’s compliant service boundary. A Copilot user’s chat history is private and is not made available to organizations or to Microsoft for reporting or auditing purposes. Copilot users may be subject to other methods of monitoring available to IT admins in their organization, such as internal logging, device or network logs, and other methods on their company network or devices.

This chat history feature does not require a user have a Copilot for Microsoft 365 license as this applies to activity while a user is in the web toggle (as opposed to the work toggle in the UX).

If chat history is enabled for an organization, users will need to consent to new terms of use presented to them in the Copilot UX to use chat history. Chats will be available to users as part of the Copilot UX for a rolling 30-day period before they are deleted. Users can delete their chats from chat history at any time.

If chat history is turned off, the feature will immediately become unavailable to users. Existing chats will be deleted in accordance with the rolling 30-day period.

Commercial data protection continues to apply. Prompts and responses are not retained by Microsoft.
