By ways of some bad choices I wound up with 3 Microsoft accounts. I never knew which services were on each.

In addition to those 3 accounts, I had 2 Office accounts (one for work, one personal). Notwithstanding that the O365 sign in really can't handle two accounts on the same browser (by ways of automatic redirects) - I didn't know if services were on O365 or Live. MSDN and VSTS do not support O365 login, so I had to tell my Live account to claim my MSDN keys. It's nuts.

I eventually just forget about accounts. I stopped using O365 for personal email. Don't use O365 for anything personal, you will pay hell for it (for more reasons than merely sign in).
