It's really not. I have no problem remembering or calling up the passwords or emails for my personal, Xbox, current work, previous work, or previous student (!) accounts. And yet Microsoft somehow gets them confused; I haven't ever signed in with this PC or from this ItoP address to my student account, the email no longer works, and it obviously can't access my work document...but something is tied together there and MS insists that must be the account I want to use. Private windows don't always fix it either, there's something shady going on behind the curtain.

Contact support and let them know you have multiple accounts and these issues. I thought they were going to be clueless but they were able to resolve some of these issues quickly behind the scenes.
