I'm a little nervous setting up a 2010 hybrid deployment server - I get this error:
Hub Transport Role Prerequisites
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!
