As we've talked about before, we're focused on delivering connected devices and services to you, our customers. And Microsoft account makes your experiences on devices and services more personal and relevant. When you sign in to any device or service with your Microsoft account, your personal settings, contacts and other information meet you there. It keeps you connected to the people you care about on Facebook, Twitter, LinkedIn and other services. It all just works, wherever you go.
One of our principles is that we should adapt to how you want to work, not vice versa. This is why we allow you to use any email address to sign in to your Microsoft account. We've also heard from you that over time things change with your account--you might get married, start a new job, move or any number of life events that make you want to change your email address. We want to make it easier to keep your account up to date as these life events happen.
