Recently, I was trying to perform an audit search on an Office365 organization and found auditing wasn’t enabled. When I tried to do it straight from the audit screen, I encountered this error:
I went straight to PowerShell and ran Get-AdminAuditLogConfig | FL Unified* and it was not enabled.
To resolve this, I ran Enable-OrganizationCustomization
And then I ran the Powershell command Set-AdminAuditLogConfig – UnifiedAuditLogIngestionEnabled $true
And that did it!
