I have the child domain scenario on my environment
Parent domain abc.com and the child domain is child.abc.com
I have two Exchange servers setup in one Exchange Org which are exch1.abc.com and exch2.child.abc.com.
I found that I can view the exch1 queue from exch2 ESM but not vice versa. I can't view exch2 queue from exch1 ESM. Appear Default SMTP and Exchange MTA with red exclamation mark
I have checked that all exchange services was started for both servers.
Currently all the exchange server are on the same First Administrative Group.
Both exchange are logon to their own domain using Adminstrator account
At the same time, moving mailbox from child to parent domain is OK but not for vice versa
