I have an Exchange 2003 server with SP2 running on Windows 2003 SP2, my external uses POP there emails. Everyone is working fine, then a few days ago I setup a new user, and this new user cannot pop the emails in the normal way. All settings are the same as other users. Settings under the Outlook account = Username - Servicesusername, then password. Services is our domain. POP3 server - pop.domain.co.nz, and smtp is which ever ISP they are with e.g smtp.xtra.co.nz - this is working on all other clients. I monitor our internal firewall, but nothing is getting blocked. I have restarted the POP3 service and SMTP service - any areas I should look???
