A PST is a local file on your computer in which your messages are stored. Some people use this in lieu of keeping their messages on the Exchange server. You will have to check your account settings in Outlook to see if this is the case for you. What I suspect is happening is that your messages are being removed from the server, which will remove them from your BlackBerry.
