I have a Exchange hub 2007 and 2010, MB server 2007 and 2010, Edge 2010 and CAS 2007 and 2010 Exchange 2007 SP2 Exchange 2010 RU3 Both Exchange 2010 and 2007 are in same site and same AD Forest/Domain Due to some reason we must need to keep both version i found when the moderation message come into Exchange hub 2007 first, the moderation function is not work (cannot be moderated), it will direct go to recipient The message route is below Message -> Edge -> Hub 2007 -> Hub 2010 -> MB 2010 (Moderation not work) Message -> Edge -> Hub 2010 -> MB 2010 (Moderation work) any setting need to care, if no, Does it has any workaround

Hi hidewu, Moderation requires Exchange 2010 to be deployed on all Hub Transport Servers to work properly. Earlier versions of Exchange will ignore moderation and simply deliver any messages to moderated recipients.

which mean when message come to only Exchange 2010 hub is can be moderated, right? When came across Exchange 2007 first, it will not moderated, right?

But in my case it will also come in to my exchange 2010 hub. So Message -> Edge -> Hub 2007 -> Hub 2010 -> MB 2010 (Moderation not work) is the Exchange behavior right?

So how can i make exchange 2010 hub always receive a message from my edge server first? than may be go to exchange 2007 or other exchange 2010 hub than mailbox server In Edge Sync? Thanks for help

i think i can modify the receive connector in EDGE sevrer and point it to Exchange 2010 hub
