title: Cannot delete blob: There is currently a lease on the blob and no lease ID was specified in the request
body: <p>When I attempt to delete a blob from my storage account container, I get an error message, "<strong>There is currently a lease on the blob and no lease ID was specified in the request.</strong>"</p>
  
  <p>I have 4 virtual machine instances. I also have 8 virtual machine disks, 4 of which are in use (one by each of the virtual machine instances). Strangely, I have 10 blobs listed in my single storage account's lone container, called <strong>vhds</strong>. Here is <a href="http://i.stack.imgur.com/rx9bh.png">a screenshot of the 10 blobs</a>, highlighting the two that I cannot delete.</p>
  
  <p>Can anyone give me guidance on how to delete these blobs? I have no use for them and I'd like to cut down on my storage costs for my subscription.</p>
