Allow to use owned org domain as an MSA account when subscribing to live.com account
When subscribing to Azure, previously it was allowed to register new live.com account with email@example.com even if myorg.com was Office 365 subscription as long as there was no such address registered on live.com already. With the most recent update with Active Directory, the domains owned by the company is no longer allowed to be added as an MSA (Microsoft Account).
Microsoft becoming as bad as Apple. 'Here is a new feature that works for all the sheeple, but for you 1/10, we don't care and wont allow you to accept the risk and consequences yourself'
My tenancy has 2 users. Until I can merge Azure AD and MSA accounts, and use Azure AD to login to all MS products (incl XBox Live, Groove, etc) this 'feature' is just an imposition that has cost me an hour just to understand that Microsoft doesn't care what you think.
