Microsoft Purview | Data Lifecycle Management: Separate Copilot retention policies from Teams chats

Updated June 16, 2025: We have updated the timeline below. Thank you for your patience.

Admins can follow the in-product message while editing the policy and make the required changes using PowerShell cmdlets to configure a Teams chat policy or Copilot policy. If there are existing policies covering other locations together with Teams chat and Copilot interactions in a single policy, admins can create equivalent new policies including the other locations from UI or using PowerShell cmdlets.

Before this rollout, Microsoft Teams chat and Microsoft 365 Copilot interactions are available together to be included or excluded in the Microsoft Purview Data Lifecycle Management policy in the Purview compliance center.

After this rollout, admins can have separate policies for Copilot interactions. Also, admins can separate Teams chat from Copilot interactions to create new retention policies for Copilot messages only.

A Microsoft 365 Copilot license is required to use this feature.

This message is associated with Microsoft 365 Roadmap ID 407897.

When this will happen:

Public Preview: We will begin rolling out early May 2025 (previously early March) and expect to complete by mid-May 2025 (previously mid-March).

General Availability (Worldwide): We will begin rolling out mid-September 2025 (previously early June) and expect to complete by late September 2025 (previously late June).

How this will affect your organization:
