1 million users sign up for Outlook.com in six hours

Outlook.com has seen more than 1 million people sign up for the service in just a few hours, Microsoft has said.

The sign-up figures for the successor to Hotmail were tweeted by @Outlook yesterday just over six hours after the new service was first announced.

The changes include the new email address -- @outlook.com -- which will replace the older @hotmail.com address, used by hundreds of millions worldwide across its more than 10 years of its service. Users can already "Upgrade to Outlook.com" to keep their existing address.
