Currently I have 2 Exchange 2007 SP1 Edge/Forefront servers on the perimeter network with 2 IronPort C350 boxes in front of them so inbound mail flow is IronPort>>Edge>>Exchange 2003 Organization. Outbound mail flow is the same path in reverse. Once I install the Client access servers and Hub transport servers I am wondering what will change on the Edge servers once I enable Edge Synchronization with the HT servers. I'm assuming the setting for the send and receive connectors will be overwritten. Will this affect the send connector that has the IronPort boxas a smart host? We have numerous authoritative accepted domains that I had to manually enter on both Edge servers. Will Edge Sync overwrite those? If so, will it pull the domains I have set in the global settings of the Echange 2K3 organization? Are there any other specific settings that I should be concerned about before I set up Edge subscriptions? Any input on this would be greatly appreciated. Thanks.

once the Edge Sync is subscribed Exchange will automatically forward an configuration information to the Edge server that is pertinent to it's operation. You don't have to 'refresh' the sync (unless it breaks somehow, then in that case simply reestablish it with the same process you used to originally set it up).Jeff Schertz, PointBridge | MVP | MCITP: Enterprise Messaging | MCTS: OCS

Great. Thanks. I'm assuming that any transport rules I have on the Edge server will be synched with the subscribed HT servers.
