On-premise Exchange server interfering with Office 365 Mail

csciarro asked
Last Modified: 2015-05-13
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?
