Setup Managed Backup failure
Issue identified.  The network admin didn't have the separate Azure domain environments trusted, although he said that he did.  I tried this and failed in our SQL DEV environment/domain in Azure, which isn't trusted.  I then, for sake of troubleshooting and communicating to the powers to be, tried it from our SQL QA environment/domain in Azure and it worked flawlessly!  The network admin compared the two environments and found the issue. Network issue after all.
