I am trying to use POP3 to access Emails from outside the organisation. I have set up secure POP3 connectivity through the firewall and I can receive Emails and leave a copy of the Email on the server. However, when I try to send Email I get
550 Requested action not taken:mailbox unavailable
In Outlook I am pointing both the Incoming mail Server (POP3) and the Outgoing (SMTP) to the Firewall address that NAT’s through to my Exchange Server.
How do I get the Exchange server to send the mail through the default SMTP Connector?
It is Exchange 2003 SP2
Any help would be appreciated.
