Before attempting to resolve the problem of Outlook Not Receiving Emails, check in the Junk Folder, not the same as the Spam Folder. Make sure you've checked your Outlook Junk folder before taking any drastic measures. It's conceivable that you got the email but Outlook marked it as junk. Simply click on the outlook message, click to Actions > Junk Email, and mark it as non-junk. This will move the email to your inbox and prevent the same behavior from happening again for the same email address.
