I have a NT 4.0 domain with a an exchange 5.5 server. By using OWA we can not access public folders that contain contacts because the version of OWA in exchange 5.5 do not support that. One consultant suggested my boss to install a separate windows 2000 domain with exchange 2000 in it. He told me to create 2 way trust between my current NT 4.0 domain and the windows 2000 domain that he wants us to build. Then create accounts for each employee and mail enable them. I had implemented all this in a test emviroment, my problem now is that in order for the people in the NT domain to read their e-mail in the exchange 2000 server that is in the windows 2000 domain they must log off from the NT domain and log in to the windows 2000 domain. Is there any way that I can implement such scenario and have my NT users read their e-mails without having to log off and login to the windows 2000 domain. P.S.: The reason for such situation is that the company do not want to migrate their domain to windows 2000 yet but, will like to use exchange 2000 instead of 5.5. Any suggestions will be accepted.
