Unable to create Service Bus Namespace, says it's already there

Question

I have deleted a Service Bus namespace that was a standard Sku, and have deleted it. I'm trying create a new Service Bus namespace with the same name with a Premium sku.
Azure is telling me that the name already exists in the subscription.

@Dave Richardson Thanks for reaching out. This issue occurs because Azure Service Bus namespace names are globally unique. Even if you’ve deleted a namespace, the name remains reserved and cannot be reused immediately. This is to ensure data integrity and prevent potential conflicts.

If you’re still seeing the “name already exists” error, it’s likely that the namespace name is still in the process of being fully deleted, which can take some time. You might need to wait for a while before the name becomes available again.

you can also verify the availability of names while creating a namespace via a rest api call [https://learn.microsoft.com/en-us/rest/api/servicebus/stable/namespaces-check-name-availability/check-name-availability?tabs=HTTP] (https://learn.microsoft.com/en-us/rest/api/servicebus/stable/namespaces-check-name-availability/check-name-availability?tabs=HTTP)

please let me know incase of further queries, I would be happy to assist you.
