I am very sure I saw something within the last year saying that you could disable the Personal side of a Microsoft Account. Of course, we know that a user, name@company.com has both a Work or School account and a Personal account associated with that same email address, confusingly. I definitely recall reading the personal side could be disabled in order to avoid that confusion for employees. Now I can't find this anywhere. It was something done by the user themselves, not like a group policy setting or any admin level thing, as I recall.
Can someone point me to this process? Thanks.
