This option uses only an [ad hoc SAS](batch-transcription-audio-data.md#sas-url-for-batch-transcription) URI and doesn't support [Trusted Azure services security mechanism](batch-transcription-audio-data.md#trusted-azure-services-security-mechanism). This option also doesn't support Access policy based SAS. The Storage account resource of the destination container must allow all external traffic.

 If you want to store the transcription results in an Azure Blob storage container by using the [Trusted Azure services security mechanism](batch-transcription-audio-data.md#trusted-azure-services-security-mechanism), consider using [Bring-your-own-storage (BYOS)](bring-your-own-storage-speech-resource.md).
