I have added my domain to office 365, but I don't want to move the dns management to office 365. I have read the article
Add your domain to Office 365 without redirecting your name server records to Office 365
and have added the appropriate dns records. My email appears to be working fine which is great, but I can't seem to finalize the add domain process. I am stuck on the last step which seems to be requiring me to change my name servers for the domain. I have to click on the button "Done, go check" which seems to check if I have changed my name servers for the domain which I am not doing. I can't seem to finalize without finishing this step and if I don't finalize I can't add additional domains.
