Since this is a transient backend database exception, Microsoft support engineers need to review service logs to identify the root cause and provide a mitigation.
The Microsoft.Exchange.Hygiene.Data.TransientDALException is a Data Access Layer error indicating that the Exchange Online PowerShell module is failing to communicate effectively with Microsoft's backend hygiene databases. Because this is a backend service issue, it cannot be permanently resolved by client-side troubleshooting.
