Outlook is seriously broken! 10 minutes after creating an account, my spam mailbox had already 20 messages. I don't believe that spammers are mailing every possible combination of a username; there must be some leak or other way. Also it seems that Microsoft gave up on verifying whether your message is spam or not. I had government emails (USPS, for example) as well as emails from my gmail and yahoo friends landing straight in junk.
