<p>Microsoft announced Thursday that it had accomplished the herculean task of moving hundreds of millions of users from venerable webmail service Hotmail to the sleek new Outlook.com. Some 300 million users and 150 petabytes later, Hotmail is officially a ghost town.</p><p>And it's been a welcome change for most users: Hotmail was around since the early days of Web-based email, and while it got a few facelifts along the way, its age was apparent. Outlook.com, on the other hand, we found to be attractive, powerful, and generally a great option for emailers of all stripes.</p><p>So Microsoft may not have had the problem of users vehemently protesting relocation, but that doesn't mean it was easy. Hotmail was a popular service, and all those years of emails and attachments add up. The company had to migrate 150 petabytes of data to the new service that's 150 million gigabytes.</p><p>It took about six weeks to do the job (as planned), but it's all finished now.</p><p><a href="http://www.nbcnews.com/technology/technolog/great-migration-hotmail-outlook-com-complete-6C9767779">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.nydailynews.com/news/national/hotmail-article-1.1334429">Hotmail RIP: Microsoft completes Outlook.com migration</a> (New York Daily News)</p><p><a href="http://www.usatoday.com/story/tech/personal/2013/05/03/microsoft-hotmail-outlook/2132073/">Hotmail is officially dead: Microsoft shifts to Outlook - USA Today</a> (USA TODAY)</p><p><a href="http://www.sfgate.com/technology/businessinsider/article/Hotmail-Is-Really-Officially-Dead-As-Of-Today-4483335.php">Hotmail Is Really, Officially Dead As Of Today (MSFT)</a> (San Francisco Chronicle)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dKWYKoD2LtEqqhMvFdVNAxszUMozM&ned=us">106 additional articles.</a></p>
