I would like to suggest a change on the Community Registration page where a note should be added below the e-mail address box when trying to register with O365 Accounts that "The O365 e-mail address is in the organisation's hands and the account will remain with the organisation even when you leave the organisation.", something like that. I am suggesting this because I have seen a lot of community posts where users want to transfer their profile to another O365/MSA account because they are changing/leaving the organisation but those accounts go into vain just because this website could not transfer that. This note will act as a precaution to likely stop these happenings.
