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.

Office 365 content searches now support a hard-delete (permanent deletion) option for the purge action, but only for mailbox items. You can purge up to 10 items at a go. If you have more to purge, you just have to keep on purging until everything is gone. Or use the Search-Mailbox cmdlet, which keeps on proving its usefulness to administrators who need to remove lots of mailbox items quickly.
