Hello Roger,

Welcome to Microsoft Q&A, If your Event Subscription is set up but nothing lands in the Blob Queue, it’s likely due to one of these common misconfigurations or missing steps. Azure Event Grid doesn’t send events directly to Blob Queues, it supports endpoints like Webhooks, Azure Functions, and Azure Service Bus. To route Blob Storage events to a queue, you need to use Azure Storage Queue as the destination, not Blob Queue. Blob Queue isn’t a valid Event Grid destination. Make sure:

You’ve selected Storage Queue as the endpoint type during Event Subscription setup.

The queue exists and is in the same region as the storage account.

The storage account has proper permissions and Event Grid is enabled.

You’re reacting to supported Blob events like BlobCreated, BlobDeleted, etc.

For full setup steps and supported scenarios, check Reacting to Azure Blob storage events (https://free.blessedness.top/en-us/azure/event-grid/event-schema-blob-storage?tabs=cloud-event-schema#reacting-to-blob-storage-events)

Hello @Roger Leung (SUP)

Could you please provide the answers for these follow-up questions to get a clearer picture of your setup:

What type of Event Subscription did you create? (e.g., Storage Queue, Event Hub, Event Grid etc.)

Are you receiving any error messages or logs that could give more insight into the problem?

Can you confirm that the Storage Queue exists and is accessible?

Hi Roger Leung (SUP),
Could you please check below.

Confirm that the Storage Queue you want to use exists and is in the same region as your storage account.
Check the permissions associated with the storage account to ensure Event Grid has the necessary access rights. Event Grid needs a SAS/key or a managed identity with Storage Queue Data Message Sender role (if you’re using managed identity). If auth fails deliveries will be rejected.
Make sure you are reacting to supported Blob events such as BlobCreated, BlobDeleted, etc.
If the storage account has firewall/VNet restrictions, Event Grid may be blocked unless you allow trusted services or use a system-assigned identity + correct configuration.
Advanced filters / included event types in your subscription’s filters might be excluding the incoming events.

Please share requested information if you're still facing the issue and need any further assistance on this.
