Running Exchange in cached mode over MPLS VPN without duplication
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,
Haris

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Exchange will not recognise the items as being the same. While the messages will appear to be the same, then internal message ID will be different and you will get duplication.
The content either has to go up to Exchange from Outlook or come down from the Exchange server. There is no other option.

Thanks for the prompt response. Your solution is pretty much what we thought, however, syncing all mailboxes in either direction is going to take too long. Of course, we could do it in instalments over night or, like you suggested, just Calendar/Contacts etc….
However, what about importing the PST file into the cached version of Outlook in Germany and locally on the server in London. Do you know whether Exchange will realise they are the same and sync more quickly or will it just duplicate everything?
Thanks in advance,
Haris
