Hi It seems the OWA does not work properly internally either so I'd rather solve that and try to publish later. I can connect to http://192.168.1.1:9010/exchange the page loads partially and says 'done' in the browser but the message area just says loading and stops there. If I click Options or Folders I am constantly asked for a Login but any valid user/password seem to be useless. Any ideas so I can get things to work internally first. William
