Exchange 2007 topologie issue
Posted on 2010-09-16
We have a main Microsoft forest with multiple sites around the world.
Each sites are connected to the headquarter in Brussels by VPN tunnelings. In Brussels, we decided to install a few months ago a first exchange 2007 server with 4 roles (Mailboxes server, CAS server, UM server, and hub server) and a second one with the Edge transport server (to filter all Spam).
On each satellite offices, the users are using the microsoft oulook client 2003 / 2007 but configure to use Outlook anywhere (RPC connection through HTTP). We are meeting latency time for these clients to reach the exchange server in Brussels and during the day, by period, the messages are blocked in the outbox a long time (30 minutes). This case is general on all remote offices (with very good Internet connection too) and we suppose that the outlook clients are configured perfectly.
My question is how can I improve this exchange topology? My first idea was to install exchange server too on the remote offices but I would like to leave all mailboxes stored in Brussels (to backup them easily). Do you have better ideas?
I hope I was clear in my explanation with my bad English...
