Original KB number: 3054391
When you run the Search-AdminAuditLog or Search-MailboxAuditLog cmdlets in Exchange Management Shell together with a Cmdlets or Parameters parameter to filter the results, an empty result set is returned. Even if you run the
Search-AdminAuditLog cmdlet without parameters, the full results may not be returned as expected.
This issue occurs in Microsoft Exchange Server 2013 and Exchange Server 2016.
