I recently installed new non-MS software, after which POP3 stopped working. It is enabled, shows it is working, but the 110 port is closed and offers no POP3 support. I have had to switch to IMAP, but because of email 3rd party software I need the POP3 working. Is there a way to just reinstall POP3 or reinstall Exch. ( 5.5 SP3) without losing all my settings and users?<br><br><br>Thanks in advance<br>Ron
