On-premise Exchange server interfering with Office 365 Mail

I recently setup Office 365 mail on my network and to do away with our onpremise Exchange server. I changed the MX and CNAME records to port to Office 365 but when I setup the users 365 email on Outlook it doesn't autodiscover and I keep getting the login pop-up. I also removed the mail and autodiscover DNS records on the onpremise server. Do I have to disable anything on the Exchange 2010 server?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Did you disable the SCP? Easy way to solve this issue is to 'instruct' Outlook to bypass the local server discovery by using the registry keys in this article: http://support.microsoft.com/kb/2212902

All you need for EO/O365 is the HTTP redirect method to work, you can block all else. And this doesnt require you messing with the local infrastructure in any other way.
