Im trying to get more information about Exchange Routing Groups. Id like to know when they should be used and the benefits of using them. What are the pros and cons when using them vs. pros and cons when not using them.

We are running Windows 2003 on all servers.
We have a backend and a front end exchange servers in our main office.
We have one Forest, Domain and Exchange Org.
We are using Exchange 2003 SP2

We have a remote office that will have an Exchange server and two DCs.
The remote office has 10 people but can grow to about 40 in the next 24 months.
Our connection to this remote office will be over a 10Mb VPN link.

Should we be using two routing groups or keep the remote exchange server in the same routing groups as the main office?

I've read a bunch of articles but am trying to make sense of it all.

Thanks,
Mokn

This article is a good one, unless you've already read it: http://searchexchange.techtarget.com/tip/1,289483,sid43_gci1113741,00.html

The whole point of them is to reduce internet connection use by designating bridgehead servers at each site. When a mail is say sent from head office to 10 people at a remote site, if the 10 people are on different Exchange servers and those are in the same routing group as Head Office, Exchange will send the message 10 times of the VPN link. If a separate routing group were set up for remote site (with a routing group connector to link the two), then the message would be sent to Head Office's designated Bridgehead server, which would connect to the designated bridgehead server at the remote site and transmit the message once for all the mailboxes at that site. It is then distributed to the appopriate Exchange servers over the LAN link at the remote site.

You should split your sites up in to 2 routing groups and use a routing group connector. If you get more remote offices, you'll need to look at your connection topology to make it robust (the article shows and describes a few).
