<p>Since we launched the Outlook.com preview a few days ago, we've been humbled and amazed by the reception and by the number of people who have upgraded. In fact, in just the first few days alone, we've seen several million people upgrade to Outlook.com. Over the next week we'll write a series of posts covering upgrading and using Outlook.com, starting with this post covering upgrading from Hotmail, and then followed by posts discussing upgrading from Gmail, Yahoo, and other services. These are all written by Dick Craddock, who runs the Program Management Team for Outlook.com.</p>
