Office 365 Exchange 2016

Trying to setup the connection between Office 365 and On-Premise Exchange 2016. In order to move from On-Premise to Office 365.

However, from Office 365 unable to reach On-Premise Exchange Server. I have setup the Exchange General Rule, using the SSL cert and configured path specific routing to point to the internal Exchange Server with Authentication = None

OWA from external is working just fine.

What am I missing?

Which one of the files do you think I should import for what is needed?

I have imported the 'all'

So of the 100 exceptions, which ones do I enable for what I am trying to do? Surely not all 100?

Also, are these Web Exceptions for LAN to WAN?

I do not see any traffic coming in for this issue.

Has anybody else got O365 to communicate to an on-Premise Exchange Server to allow migration of On_premises mailboxes to O365?
