Is there any good reference and any experience which version of Exchange partner server(2007 or 2003) is more reliable ?
Only I found that when I try to use exchange 2007 as a partner server, due to script, this partner server should be physically connected, not support by remote.
Is there any other issues such as MWI delay experience, Unity Networking delay should be considerated.
My site should be run Unity Digital Networking with failover.
As I remembered the rule of a partner server, outside unknown message pass through partner server, hence, This is not related to performance exchanage version.
any idea is welcome and appreciated.
