Yes.  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.

Thanks for that.

Daniel.
