I'm trying to set up a new exchange server and have everything configured to send e-mail and receive through outlook web access and standard exchange access. However I can't get the email through POP3. I've enabled the service, added firewall rules.
If I set up the account in outlook for POP3 access and do the "Test Account Settings"
"Log onto incoming mail server (POP3)" shows as completed as if it works.
Once I close this, and do a send/receive I get the following error.
Task 'email@....net - Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: -ERR Server Unavailable. 21'
