Limits in eDiscovery (Standard)
Important
This article applies only to the classic eDiscovery experience. The classic eDiscovery experience will be retired in August 2025 and won't be available as an experience option in the Microsoft Purview portal after retirement.
We recommend that you start planning for this transition early and start using the new eDiscovery experience in the Microsoft Purview portal. To learn more about using the most current eDiscovery capabilities and features, see Learn about eDiscovery.
