Exchange 2016 to O365 Hybrid Migration Mail Flow
I'm performing an On premise Exchange 2016 CU3 migration to Office 365. (I've not done this before). This is a test domain, it will never be used in production, this is just an exercise so I can run though the process, before I have to do it live.
Steps taken;
There is no mail flow, outbound mail leaves the queue from Exchange 2016
Inbound mail does not arrive.
Exchange Connectivity Analyser tells me inbound mail is fine, but it isn't?
I cant find one DECENT article, on Microsoft or anywhere else, that walks you though an Exchange on-prem to Office 365 Hybrid Migration!
What am I missing/What have I done wrong?

Steps taken;
- Azure AD connect has been installed (and has Synced).
- Domain has been setup (and verified) in O365 Admin.
- Hybrid Wizard has been run through, and completed successfully.
- No users have yet been migrated into O365.

The folk at M$ tell me the connectors are not working, this may be because my on premise is now not healthy, Im just putting CU8 on it (good job its not in production!)

OK Im making progress - ECP/EMC were broken because they had managed to get the wrong cert on the IIS back end - thats all working now.
Mail inbound (via O365) is now working!
Mail Outbound is NOT working, there's nothing on the outbound queues, the firewalls not blocking mail flow, I can telnet from my Exchange to other mail gateways on port 25, my public IP is not blacklisted. I'm assuming outbound mail just goes out locally from my on-prem exchange server?

Should I still be able to open the local Exchange Admin Center ie https://mail.DOMAIN-NAME.co.uk/ecp and I should still be able to open the Exchange Admin Shell (PowerShell) on my on-premise Exchange Server? Because they both don't work, and I'm not sure if that's normal after running the hybrid wizard
