Important Purview eDiscovery Changes Take Effect in May 2025

Microsoft is making some important changes to Purview eDiscovery from May 26, 2025. The changes affect how content searches work and are likely to affect many Microsoft 365 tenants. Administrators and eDiscovery investigators will both have to master new ways of working with eDiscovery cases, searching for information, reviewing search results, and exporting what’s found. Changes to PowerShell cmdlets might affect scripts, so there’s lots to consider.
