exchange 2007 and 2003
Posted on 2011-10-25
Hi folks thanks in advance
We are in the process of migrating from exchange 2003 towards exchange 2007. Normally its a "simple" procedure. But in this case, due to geographical locations and volume of data we will need to run both 2003 and 2007 servers for quite some time.
So my question is this, if i am running both 2003.2007 OWA/mail servers side by side, then how are the incoming emails are routed between the two servers?
When an email comes in, how is it determined to which email server the message is transferred to?
