Exchange 2013 - Emails for a secondary location

Have a customer that has two locations - main office and a satellite office. They are connected via a site-to-site VPN (10x10). The users at the satellite office complain about the speed of email all the time (they send some decent sized attachments). Thought was to put in another Exchange 2013 server at the satellite office and put the users at that location on that server on a new mailbox store.

Is that the best way to do this? Do I need to do anything special for those users to have access to OWA and/or ActiveSync? I would prefer not to have a 3rd Exchange server in the mix.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You don't need a third server for that location.
All roles on the server would allow access.

With regards to remote access, you have two options.
1. Give the server its own URL, and have them connect directly.
2. Ensure that there is no external URL configured and then Exchange will proxy the traffic over your VPN connection.

Although if they are sending large attachments to external parties, it isn't really going to help very much.

Where am I leaving out the 'external URL' ?
Simon Butler (Sembee)ConsultantCommented:
Virtual directories of the second server.
mvalpredaAuthor Commented:
Which virtual directories? For all services?
Simon Butler (Sembee)ConsultantCommented:
If you want the connections to proxy then all virtual directories on the second server need to have no external URL configured. That tells Exchange the connection is proxy. If the external URL is populated then Exchange will attempt to redirect to that location.
