Retention policy for only Microsoft Copilot Chat and Copilot Studio agent transcript?

For the documented Microsoft Copilot experiences retention location, Microsoft groups Microsoft 365 Copilot, Copilot Studio, Security Copilot, and Copilot in Fabric together. The policy's Choose and Exclude controls refine the users in scope; they are not documented as a picker for individual Copilot products.
Therefore, I would not treat that location as supporting the requested product-only exclusion for the same users. First identify whether the different products are used by separate user populations; user scoping may meet the requirement in that case. If the same people use all four products, ask Microsoft support to confirm any newly available app-level scoping before deploying the policy.
Also distinguish collection from retention: Security Copilot and Fabric interactions require content collection for these retention scenarios. Changing collection is not equivalent to excluding already collected content. Validate the intended outcome through eDiscovery, with your compliance administrator, rather than relying on visible chat history.
