MC432476: Microsoft Purview | eDiscovery (Premium): Retirement of classic case format

We’re retiring the “classic” case format option from the eDiscovery (Premium) case creation page starting November 1, 2022. Instead we recommend the utilization of the eDiscovery (Premium) “new” case format, which features improved performance and additional capabilities, and where we will continue to invest our development resources.

MC432476: Microsoft Purview | eDiscovery (Premium): Retirement of classic case format

How this will affect your organization

You are receiving this message because your organization has access to the eDiscovery (Premium) solution.

Starting November 1, 2022, all new eDiscovery (Premium) cases created will take the new format by default. The option of classic format will not be available on the case creation page. Any existing eDiscovery (Premium) cases in your tenant will still be accessible and can be operated as normal.

Starting February 1, 2023, existing collections and review sets in active classic cases will become view-only. This means any existing collections and review sets cannot be edited but will still be accessible. New collections and review sets can be created in these classic cases if needed. Newly created collections and review sets in existing classic cases will take advantage of the new case format processing pipeline and enjoy benefits such as increased collection and review set limits (1TB instead of 300GB).

For existing active classic cases with collections and review sets that will need to be preserved but won’t need to be edited, data will still be accessible and can be exported beyond February 2023. The classic case format retirement should not affect this scenario.

What you need to do to prepare

If your organization has not yet evaluated the new case format, please do so to ensure you have enough time to assess how these changes will impact your organization’s eDiscovery workflow. Be sure to provide training to all eDiscovery users in your organization on the new case format and update relevant documentation if needed.
