I am trying to find documented proof that supports the answer to the following scenario.
We are currently utilizing Cached Mode for outlook clients but are put into a scenario where we need to move everyone's data off of the server and into pst files locally on thier pc. These are hundreds of users most of which are behind bonded T1 connections.
My question is when instructing users to perform this action, does the mail move from the ost into the pst locally and then the client and server synchronize or does the traffic come from the server to the pst file? My concern is bandwidth utilization since many of the mailboxes are quite large.
