Exchange 2003 POP3 Can telnet to port, but can't get email
Posted on 2009-12-18
I've setup a new OWA server and we have some old clients that need POP. OWA works fine, but I setup POP (enabled services, started default POP protocol, have it set to accept all connections, etc.). I can telnet to the port just fine and get a header, but when I try to connect to the server with a POP mail client I get an ERR connect attempt failed, server may be down or too busy to respond.
So I'm stumped, all other solutions deal with making sure the setup is correct and you can telnet to the port, mine is and I can, so not sure what to do next.
