Email verification?

I created a new account a couple days ago and used my outlook.com email address. Despite repeated attempts, across multiple days, I never received an "email verification" message from the forum, and thus was unable to reply to threads or create new threads. I even checked my junk folder and found nothing from the forum. Today I changed my email to use one of my other email addresses, which uses a different domain, and I received the "email verification" message from the forum immediately.



Is there a reason I can't use my outlook.com email address for the tivocoummunity.com forums?
