Edge Sync Use Specific Hub Transport Servers

Question
-
Hi,
I am setting up an Edge Synchronisation for mail flow to Exchange Online (Hybrid). I would like the email destined for Office 365 to route via my new Exchange 2016 Mailbox servers and then to the Edge Transport servers, and not use the old 2010 Hub Transport servers to route direct to the 2016 edge servers, however there doesn't seem to be a way to achieve this from what I can tell? How can I force the Edge to Internet send connector to route email via my new 2016 Transport servers before sending to the edge?
Thanks.
Mike.

Hi Mike,
Theoretically speaking, yes.
If you follow the link I post, you need to add only the FQDN of Exchange 2016 as "Source servers“ in Step5 and add only the FQDN of Exchange 2016 as ”Smart Host“ in Step2.

Hi mike,
Did you run Edge Subscription?
If you use Edge subscription, it will create send connectors on both servers and disable the command of creating and modifying the connectors.
If you manually created the connector to Edge server, just modify the "Source server" of the connector as Exchange 2016 server name and it will route though the 2016 Server.

Hi Eric,
Yes I have run the edge subscription. Can I delete the connectors that were created with the subscription and re-create them manually?
The problem I see is that the send connector needs to have the edge transport server specified as the Source Server. How will I add the 2016 Mailbox server as the first hop in this scenario?

Hi mike,
You should remove Edge Subscriptions, after that the connectors will be removed automatically. Then you manually create send connectors and set the Source server as I mentioned.
This link should give you some guidance:https://docs.microsoft.com/en-us/exchange/architecture/edge-transport-servers/configure-without-edgesync?view=exchserver-2019
"The problem I see is that the send connector needs to have the edge transport server specified as the Source Server."
- Actually I am talking about "Source server" of the connector on Mailbox servers, not the connectors on Edge server.
I can't conclude this method will work but it should worth a try.

Hi Eric,
Thank you again for the response. So just to confirm, the exchange 2010 Hub Transport servers will send directly to the Exchange 2016 Edge Servers by default and the 2016 Edge servers will send to the 2010 Hub Transport servers when email is sent inbound? The only way to prevent this from occurring is to remove the edge subscription and manually create the connectors?
Thanks,
Mike.

Hi Eric,
Thanks for the quick reply, I do have one more question. I will manually configure the routing via the edge servers to achieve mail flow through the 2016 servers only, but I will not be using the Edge Transport for internet mail flow. They will only be used to route Hybrid Exchange traffic to and from Office 365. Is there any documentation that details how to setup these connectors manually for Hybrid or will be hybrid configuration wizard create all of the required connectors for me?
Mike.
