Quick question, we are looking for the best way to mitigate data synchronization over our WAN after a large Exchange migration. For example, we have just taken a 250 user company with 450gb of mail into our system. With this project it was all or nothing, they needed access to all mail from day. So that meant that from day 1 to day 7 they were still synchronizing their e-mail to their local OST files via Outlook client. This used around 20Mbps over their various lines and really slowed their WAN down.
Would there be a way to move e-mail for our clients to an e-mail server in our data centre, where it is then essentially cloaned with software like Quest or DoubleTake. Once the Exchange server is synchronized in our DataCentre, we then take it to site and synchronize it again. When done, we connect outlook clients to the local Exchange server onsite, when OSTs are built, then point outlook back to the Exchange server in the datacentre, or would that still invalidate the OST and cause a re-sync?
