Hi;

I am using Exchange 2013 Standard in DAG configuration.  I want to know, if I configured a MailFlow rule on EX01, would this mailflow rule will be replicated to the EX02?  or any changes on EX01 will be replicated or copied to EX02?  I am wondering if my DAG working properly?

what Exchange Shell command can be used to detect the DAG replication issue of two servers?

I know one of the command is "Test-ReplicationHealth -Identity <server name>

Transport rules are replicated to all the servers in the org running the mailbox role and that's not related to the DAG.

Other commands:

get-mailboxdatabasecopystatus

and

get-servercomponentstate

Looks like good.  Why the rules not copied.

[PS] C:\Windows\system32>get-servercomponentstate -identity  ex02

So you create a hub transport rule that isn't being replicated?  AD replication is responsible for that, so you would need troubleshoot from an AD perspective. At a minimum, restart the Exchange transport service on all the servers.
