It does indeed look like Outlook remembers settings for old users and when presented with a new server with different configuration although using same protocol, it refuses to login. Thats why new users work well.
I thought that Outlook did not like the certificates on the new server and although it did pop the certificate acceptance prompt, I was not sure that worked. I thought of copying the certificates from the old server to the new ones. But the oldserver popa3d used no-ssl login, so no certificates. I will try the suggestion below on Monday. My other option is to present the new server to mail clients with new url and ip address (ie: mail2.company.com.au instead of mail.company.com.au). That may force Outlook to forget old settings.
