Email addresses and phone numbers associated with your Microsoft account are called aliases and they use the same contacts, online storage, subscriptions, and account settings.

Warning When removing an email alias that’s connected to a Microsoft domain (such as @Outlook.com, @Live.com, or @Hotmail.com), that email is completely deleted from our systems and can’t be used to send or receive emails. It won’t be available for use again as an alias on another account. Microsoft doesn’t recycle email addresses, so it can’t be reclaimed at a future time.

请注意 根据你所在的区域或提供商，可能会看到向帐户添加移动计费或 PayPal 的选项。 保存前，请确保所有信息都正确无误。 信息不正确或过时可能会导致在 Microsoft Store 中进行购买时出现问题。

Tips: While signing in, select Yes at the "Stay signed in?" prompt if you want to go straight to your mailbox next time (not recommended for shared computers). Alternatively, check the "Don't show this again" box and select No to be prompted for your password each time.. If you can't sign in, or have forgotten your username or password, use our sign-in troubleshooter.
