Microsoft recently released its new webmail service Outlook.com to the public. The new email service from Microsoft includes all the features and options you would expect in a good mail service. The simple, clutter-free interface is probably the highlight of Outlook.com. Outlook.com comes with some cool features to keep your inbox clean from spam messages. Even though Outlook.com includes industry leading spam protection technology, users might occasionally see spam messages in the inbox.
