Two Admin Audit Log cmdlets, `Search-AdminAuditLog` and `New-AdminAuditLog`, will retire on September 15, 2024. It's recommended to use `Search-UnifiedAuditLog` instead. Details on retirement and migration are available on the Microsoft Community Hub.
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.
