My client downgrade installed Exchange 2003 from "2007 license" 3 years ago. Now over cap. and want to install back the Exchange 2007 because without 75GB limit.
Existing email accounts need to migrate?
Now this Exchange 2003 server (location A) has one task is doing for collecting emails and then send to other Exchange 2003 servers (says Location B and Location C). If install back to Exchange 2007, any settings and impacts?
