Dynamics CRM Office 365 Server URL not found

Hi guys, I am setting up the CRM email router for Dynamics CRM in Office 365 and it is not taking the URL for the server, we are located in the US, so it should be disco.crm.dynamics.com/<organization unique name>, but when I enter that in, it sends me to a 404 on a website, and it does not work in the email router.

URL should be: disco.crm.dynamics.com/bsnconnect but that does not work.
