Hi

Recently we got Office 365, Exchange online hybrid solution.
We will both have on premise users with Exchange and office 365 users.
We have split brain DNS.

Struggling a bit with autodiscover.
How can we both have autodiscover for Exchange and autodiscover for Office 365 ?

Tried creating a cname to test:
autodisover.contoso.com -> outlook.autodiscover.com
*Cannot be created because it collides with AA Record autodiscover.contoso.com


Regards.
