You can monitor the data that you receive from an Azure Service Bus dead letter queue.
Use the Received status to decide if any troubleshooting action is required.

The possible statuses are:
Status Description
New The data is received from the Service Bus dead letter queue. Based on the Service Bus search definitions, a message is assigned.
In process The data is now imported into D365 FO by the assigned message.
Finished The data import into D365 FO is finished successfully.
Error The data import into D365 FO is finished with errors.
Invalid The data is received from the Service Bus dead letter queue. But, based on the Service Bus search definitions, no message is assigned.


Standard procedure

1. Go to Connectivity studio > Inquiries > Service Bus queue > Received dead letter data.
2. By default, only received dead letter data records are shown with status 'Error' or 'Invalid'.
  To show all received dead letter data records, clear the Show errors check box.
