Current scenario: There is a new Exchange 2003 server in London and an old Exchange 5.5 server in Munich. There is a POP3 connector between the Munich server and the London server which downloads e-mails from the London server for 10 members of staff in Munich. E-mails are then deleted off of the London server once downloaded.
We now want staff in Munich to connect in cached mode directly to their mailboxes on the London server over an existing 256k MPLS VPN. This works fine, however, we’re not sure about how to get existing e-mails back onto the London server and synchronised. Each member of staff has a mailbox on the Munich server of between 400Mb and 1Gb. Synchronising this over the existing VPN between each Munich Outlook profile and the London server is therefore probably not an option. What is the best way to do this without resulting in duplication?
Many thanks in advance,
