The users with PST files can either keep them as the archive of their old
mail, or you can move the data into the Exchange store (either manually, or
with ExMerge). You will likely want to reconfigure their default delivery
location to be the Exchange mailbox for all new mail.
An OST is created when you create the profile for a user, or can be create
later by editing the profile - all this is documented in the Outlook Help
