Clarification on definitions

Hello 1471975, your question doesn't appear to be related specifically to Configuration Manager but instead you are asking about the various Microsoft identity providers. For an intro to these concepts, you can review this blog post https://techcommunity.microsoft.com/t5/itops-talk-blog/what-s-the-difference-between-a-personal-microsoft-account-and-a/ba-p/2241897.

If you have further questions about this topic I suggest posting in the Security, Compliance and Identity discussion space https://techcommunity.microsoft.com/t5/security-compliance-and-identity/bd-p/SecurityandCompliance.

Best regards
