In setting up Exchange 2007 or 2010 server, is there still a need for the Edge Transport Server? We want something that still adheres with a single-server set-up so we’d like to know whether installing Hub Transport, Mailbox, Client Access, and Unified Message would suffice or would there be a need for another server in addition to the aforementioned servers. In case that an Edge Transport server is no longer needed, is there something else that I need to know that needs to be configured?
Setting up Exchange 2007/2010 Server
Hello Ron Barnes,
You will require the edge transport server so as to switch to either exchange 2007 or 2010 for the following reasons:
With edge transport server installed, you will be able to utilize protection benefits that it offers before you begin the process of upgrading your internal Exchange organization to the latest version of the exchange server.
It will be useful especially if you are having many sites that you will not need to upgrade all at the same time, but you still need the servers that are in those sites to send mail directly to the perimeter before they're upgraded.
Also it will be crucial in case you need to deploy Exchange 2010 so as to merge it with Exchange 2003 so that you can able to centralize mail flow through your Edge servers.
Hope this helps.
