One of my clients uses Outlook tasks which are assigned to him by other users. I tried to migrate this client (who is the owner of these tasks) into a PST by using the export function. However, I found that when I exported his Mailbox to a PST and then changed the default mail delivery location to the new PST, his reminders & tasks no longer send updates to the individual who originally assigned the task. (They appear to be gone from the Update List)
Is there any way to preserve the Update list when migrating users from the server to a PST?
