I have an Exchange 5.5 server in a mixed mode Windows server envirornment. We are located on the West coast but have aquired several companies on the East coast. A 2mb piece of email takes about 45 seconds to open for the East coast users. They have deemed this unacceptable so I need to find a solution. I do not want to put an Exchange server on the East coast because there are other factors involved in the equation. These are things like a SAN, Enterprise Vault server, OWA and anti-spam server. Does anyone know of a way to reduce the delay for the east coast users. The only thing I can think of is a >pst file but I am not really into that idea. Any help would be appreiciated.
