I have at least three different Microsoft accounts, between individual, MSDN, and Office365 variants. All of them use the same email address. I never know which account I'm going to get logged into, and I've seen some really fun OAuth redirect loops when the cookies get scrambled. Supposedly, it's possible to link accounts, to resolve some of this clusterage, but it doesn't seem to work, or I haven't sprinkled enough chicken blood about or performed the process in the hour of the wolf under during a blue moon...
