Hi, I have just got Exchange Online for one email I need synchronized on 2x computers. However, I am having trouble getting it setup. I have confirmed ownership of our domain name, and then added the email address to the 2x computers outlooks. Changes are synchronizing within Outlook as I had hoped :)

However, I am unable to send or receive emails from this email from within Outlook? There must be a setting I am missing, but I can't find this. 

UPDATE: I can send to external emails, just not to internal emails (ie. same domain name).
