Azure: There is Currently a Lease on the Blob

KB ID 0001517

Problem

This sort of highlights my lack of experience with Azure! But I had to Google it, so if you are here, you did as well 🙂

There is currently a lease on the blob and no lease ID was specified in the request.

I had been uploading .vhd files and creating VMs from them, and was tidying up, so I wanted to delete anything that had been left behind.

All Services > Disks (or Disks (Classic)) > Select the appropriate disk > Delete.
