Autodiscover for Active Sync with multiple domains

I am curious how to set up Active Sync on a single Exchange 2013 server that hosts multiple domains. This Exchange server houses multiple businesses under one roof with 7 different email domains. My SSL is a UCC SSL with the name autodiscover.contso.com & mail.contso.com. I have other domains such as blah.com, blahblah.com & blahblahblah.com..... etc.. If I create public DNS records for autodiscover for each domain all my users get an SSL warning when opening Outlook because the name of the SSL is autodiscover.contso.com.  I can't get a SSL with multiple root domains in it can I? Any other way to get this to work? I want all users to be able to enter email & password and connect right up on mobile devices.

Hi 

One is to create autodiscover.<tenant domain> and point that to the IP address of the autodiscover of your CAS boxes with the redirction, or CNAME and point to the name of your CAS box with the redirection.

I would always recommend to do a autodiscoverredirect which is best option for hosted setup. You can follow this blog

you can have multiple domain added to the SAN cert and have only one autodiscover and one primary domain for all users. Let them know what is the primary domain is. So basically they will need to use the primary domain to configure their mobile device and for OWA you can still have separate SSL for each individual domain.

For example if I had a user whose email address is user@blah.com but autodiscover only exists for  the domain contso.com, how would this work? You need some sort of autodiscover for the blah.com domain
