I have brand-new tenant and am trying to invite users to it but getting "Invitations are blocked for this directory due to suspicious activity. Please contact Microsoft support for help."

I am trying to open a case with Azure but not sure I am doing it right - is there a special group I can contact to make this go faster? It's a legit account I need up and running
