Introduction

UPDATE: August 2018
As promised below I've finally written up my 
Azure AD B2B Invitation Management Agent. 
You can find it in this post here.

UPDATE: June 2018
When I originally wrote this post the intent was to test
the ability of the Graph MA to export to Azure AD. 
That works.

That then extended to messing with an identity type other 
than member (which works to an extent) but I detailed 
guests. However that is incomplete.
