Microsoft launched their new web-mail service, Outlook.com, yesterday and they offered users an opportunity to register @outlook.com IDs of their choice and use them as an alias with their old Hotmail or Live email addresses. Some people didnt even get a chance to reserve their firstname.lastname@example.org email address but on other hand some people reserved email IDs that Microsoft should have reserved for themselves like guys over at PC Pro who got email@example.com and a Tumbler user who got firstname.lastname@example.org and email@example.com.
Some people even grabbed email addresses like firstname.lastname@example.org and email@example.com. A Twitter user succeeded to secure firstname.lastname@example.org. It is unclear what Microsoft will do with such email addresses but they can always delete these addresses.
