We have an Exchange 2000 server that was only used for inter-office messaging within an application.  This application is no longer used and all users have POP3 accounts.  When the exchange server is down, nobody is able to open outlook.  How can I set up the outlook clients to no longer be bound to the the exchange server?  Some users have mail going to personal folders and others to the mailbox.  Is there an easy way to get existing mail out of the mailbox and put into a personal folder on their new WTS server profile?  Thanks

Software/Hardware used:
Microsoft Exchange 2000, Outlook 2002, WTS server 2003
