We will be retiring the two Admin Audit Log cmdlets Search-AdminAuditLog and New-AdminAuditLog from the Microsoft Exchange Online version 3 module on September 15, 2024. Instead, we recommend using the Search-UnifiedAuditLog cmdlet for auditing, where we will continue to invest our development resources.
Please refer to Update on the Deprecation of Admin Audit Log Cmdlets – Microsoft Community Hub for details on the retirement and migration of the two cmdlets.
