Office 365 business open GPO

We just signed up for office 365 business open without hosted mail option.

We have on premises exchange server.
We pushed the settings like use RPC proxy, SSL, server name etc through office 2016 GPO.
It was working smoothly. But since the installation of office 365, I believe GPO is not working & outlook is not getting connected while travelling. Now one particular user is travelling & we realise it now. His iphone is connected with on premises exchange without VPN but Windows 10 PC with office 365 suite he can't get connected unless he connects through VPN.

Thank you for the prompt response. I have already set autodiscover but no success.
Outlook ask for the password and freezes.
Tested using Microsoft connection test analyser too.
Autodiscover is working fine.

have you added the domains to Office 365?  are they Authorative or Internal Relay?  Has DNS been setup in your Office 365 setup as well?  Are your users setup in Office 365?  Do they get synced via DirSync (AADConnect) or are they manually created in the cloud?

this article has some good information that may assist with domain validation.

We have not taken email hosting at 365. So the exchange server is on premises. Office 365 is only to get license of outlook & office applications.

I am still not confirmed if the solution would work!

But I believe the best we can do is to set autodiscover.
Office 365 does not support GPO.
