Run SMTP and POP3 on single Echange server

I have Windows 2003 SP2 domain with a primary domain controller and a backup domain controller.  I also have a single Exchange 2003 SP2 server currently running SMTP.  We have need to run some third party apps that only use POP3.  Can I run SMTP and POP3 (the service is currently disabled) at the same time and if so how do I configure it and what are the implications of email being pulled off the server by the third party app and thus not available to the user.  I am begginer in Exchange administration so please be kind and thorough. I realize this could be a stupid question to some of you.

Great!  Since I already have the users setup, how do I configure their mailbox to leave a copy on the server?
Sorry, I should have been more specific in my follow up question.  I know how to leave a copy of email on the server from the client but is it possible to force the issue from the server side.  I ask because, as mentioned above, we have some third party (offsite vendor) software that will be accessing the mailbox and I would like to force the issue of leaving copies of emails on the server if at all possible so the vendor does not end up with all the email.
Through Exchange?  I don't think it's possible.  It can only be done on the clients side.
Great job, thanks!
