We have offices in San Francisco, New York, London, & Paris. We are looking to have a copy of our information store at all locations. For instance can we have a real time copy of the New York information store in San Francisco so if the New York Server goes down users whose mailbox was located on that server can get their mailbox from San Francisco. Or if a San Francisco user flies to London and logs into the London server can we have a real time copy of his mailbox on the Exchange 2003 server there so that he/she does not have to wait for the mailbox to come over the Frame Relay from the San Francisco Exchange server? Thank you in advance for your help.
