Office 365 and Exchange 2003 hybrid deployment

I'm a little nervous setting up a 2010 hybrid deployment server - I get this error:

Hub Transport Role Prerequisites
Completed

Warning:
SMTP instance 'CN=1,CN=SMTP,CN=Protocols,CN=OWA1,CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=Bre1,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=Bres,DC=org' is configured to route all messages via smart host 'mail1'. Remove this option if this SMTP instance is set as the source or target transport server of a routing group connector between an Exchange Server 2010 routing group and an Exchange Server 2003 Server routing group.


Now, currently, we only have one routing group, so we have no routing group connectors.  We have three SMTP connectors, one that does list OWA1, and OWA1 does have mail1 set as a smart host.

My question - if I'm doing this to setup the hybrid deployment server, do I need to worry about this warning?  Will I even have to set up a routing group connector in this process?

I want to prepare, but we can't compromise our on-prem setup during any piece of this process.  

Thanks in advance for your help!

It is referring to a smart host on the SMTP Virtual Server, not a connector. You must remove it from the SMTP virtual server.

Do I have to remove it if I only have one routing group, and/or the OWA server will not be a target or source for a routing group connector?
You have to remove it no matter what.
You shouldn't have a smart host on the SMTP virtual server at all. It interrupts Exchange email delivery. Doesn't matter the SMTP connector says, all email from that server will go via that smart host.

I guess I don't understand... please forgive my ignorance.

OWA is a physical box, what do you mean by smtp virtual?  From where would I remove this setting, and what possible repercussions would that create?
Virtual was used a long time beofre VMWARE/HyperV.
ESM, Servers, <your server>, Protocols, SMTP. Right click on the default SMTP Virtual Server and choose Properties. Click on the last tab and remove the smart host. Apply/Ok out and restart the SMTP Server service.

Impact? Your email will not flow through that smart host any more. That might mean you have to set it on an SMTP Connector instead.

ok, if that OWA smtp virtual is already included as a bridgehead in one of my existing smtp connectors, removing it should cause mail to use that connector rather than the smart host - so essentially, I should see no adverse affects, rigth?
