Error when trying to activate Internal Use Rights (IUR)

I am a Microsoft Silver partner. I am trying to activate my Azure Internal Use Rights (IUR). I am getting an error during the activation process. The error message is:

"MS-AZR-0025P IS NOT AVAILABLE"

I have taken screen shots of each step in the IUR activation process using Problem Steps Recorder.  I can send them to you upon request.

I have opened support cases with Microsoft Partner Support and Microsoft Azure Billing Support.  They suggested that I post my question here for a resolution.
