We have recently embarked on a cost savings project that entails locally
housing and servicing our email servers in the U.S. We had several local
servers in the ASIA and European regions that were moved to the
headquarters office in the U.S. Obviously we knew that the performance
would be somewhat degraded because of the move from a LAN attached server
to a WAN attached server. We are receiving several complaints from our
clients that the speeds to open an email are extremely slow. An email with
an attachment is almost "snail mail".

Has anyone else experienced moving from a LAN email service to providing
the service over the WAN? What are some of the expectations and how can
you address the slow downs. The current WAN network consists of frame
relay, leased line, and VPN connections into the headquarters office from
our remote sites. Are there any performance enhancing capabilities in
Exchange or are we stuck with the latency of the WAN network?
