Outlook 2010 and 2013 does not have these hardcoded into them. Older versions of Outlook 2010, i believe older than SP2 does not support O365 completely because of the unsupported authentication mechanism.
You can check if the migrated mailbox has a valid Remote Routing Address or Target Address. Your Autodiscover configuration is correct for now you do need to point it to your on premises, and attributes like remote routing address should be able to route your AutoD request to O365.

I checked from ecp and the remote routing adress looks correct and is:
pizza@migexchange.mail.onmicrosoft.com
Where can I check the target address.
If they were wrong, shouldn't it not work with Outlook 2016?
