I wouldn't trust Tuta like Proton Tuta ran a blog post about how Microsoft was out to get them because users of Tuta couldn't create Microsoft accounts. The kick? It's because Tuta was incompetent and we're using the same domain for public users of their service as for internal corporate use. They registered the domain as an azure tenant to that point. Then we're confused why users of @tuta couldn't create Microsoft accounts. The best part is disallowing "personal accounts" with azure tenant domains is a tenant setting. But they already committed multiple levels of security breakage by mixing anonymous and corporate use of the same domain. I even tested that they infact had an azure tenant with the very domain they claimed Microsoft blocked.
