Probably nothing.  POP3 is one of several protocols that clients can use to communicate with a mail server, but it's not very feature-rich.  Outlook does not use POP3 to communicate with Exchange by default - it uses MAPI via RPC.  You'll most commonly see POP3 when you're setting up a mail client to connect to your ISP's mail server.  Stop the service, and see if anything is affected.  I don't think it will be (POP3 is disabled by default in SBS), but if users complain that they suddenly can't access their Exchange mailboxes, you'll either need to restart POP3 or reconfigure their Outlook profiles to connect to Exchange via a better method.  Of course, if you're not using Outlook, you'll have to use whatever protocol(s) your mail client supports.
