Hi,
we currently planing a new exchange 2003 installation for our company.
I am not sure which of the 2 paths would be best for us.
The situation :
3 Offices worldwide with approx 20 clients in one location and 10 in the 2
others with a potential groth of 100% per year.
The sites will be linked with VPN.
All users use mobile services like OWA and travel a lot.
1. Scenario : Each site gets its own exchange server installed. Mails get
received in 1 location and the routed to destination exchange server.
Each site sends mail through local connection.
2. Scenario : One central exchange server with VPN access and mobile access
to this central echange server.

Which scenario would make most sense ? Also in terms of growth and bandwidth
capacity and availability.

Thanks a lot,

Oli

On plain numbers the Outlook Web Access and RPC over HTTPS from all
sites into a single server makes most sense. I wouldn't envisage a
single situation where I would deploy multiple Exchange servers in
locations with that few users in, regardless of any bandwidth issues
you might have.
