We need to delete a VM scale set but it failed to delete and is now in a "Marked for deletion" state. Here's the error.

Remove-AzVmss : Long running operation failed with status 'Failed'. Additional Info:'An unexpected error occurred while processing disk. Please retry later.'
ErrorCode: InternalDiskManagementError/StorageAccountNotFound

Is there any way to delete this scale set? It says to wait longer, but for how long do I have to wait?

Thanks,
Dan

    This issue usually happens when, the resource removal is not followed as per Microsoft recommendation.

    You can try a force Update the resources reported through resources.Azure.com portal. If the resource is stuck in a deletion, or updating state the following operation helps to resolve the issue in most of the cases I see
    Visit resources.Azure.com, and find the storage account and vmss : Subscription Name > resourceGroups > ResourceGroup Name > providers > Microsoft.Storage > StorageAccounts > StorageAccountName. Similarly find the VMSS resources also.

    you may find it as shown below:

    Click Edit and then click PUT to forcefully update. Try a deletion after the above steps and see if it helps !

    I ended up contacting Microsoft Support for this issue. They had me try several powershell scripts, but nothing worked so they had to escalate the issue. they made a change (not sure exactly what that was) and I was able to delete the VMSS.
