current Exchange 2003 (a Citrix virtual machine) has slow issue. We plan to use an image (one month old) to restore it to a previous state. But we have a question. Because this image has one month less data on it, after we start to use it (before restoring mail back to clients), will it automatically remove/delete a month mail (from the day to 30 days ago) from client cached Outlook? Because restoring one month mail to everyone takes time, it will definitely cause panic in clients.
