Collectivist action is great, when it's great. But with it comes all the usual ossification problems. (For a collective to have power others have to give it to them. Either the collective manages to secure a monopoly, like the various professional licensing/accreditation bodies, legal bar association, medical residency programs with fixed number of slots. Or stakeholders - companies, professionals, regulators - have to join the collective and give up at least some of their independence during the process.) Yes, email is kind of important. But it's also pretty shoddy. It always has been. (Confidentiality, integrity, authentication, signed receipt of delivery. All are important for regular business correspondence and by default all were [and still are] hit and miss with email.) This practice of MS of not accepting email might be abuse of market power. But they can easily say their clients signed up for Outlook to have exactly this protection. What would the courts think? Who knows.
