Is there any way I can have folks with Windows 7 connect to an Exchange 5.5 server in a Windows NT 4 domain without logging into the domain as it seems that Windows 7 can't log in to an NT4 domain?

Hi, We know Windows 7 cannot join Windows NT 4.0 domain. Windows NT 4.0 domain join is not supported with Windows 7 and Windows Server 2008 R2 To connect to Exchange 5.5 server in the Windows NT 4.0 domain, I think you can try the following: 1. If your Windows 7 is Windows 7 Professional, Enterprise, or Ultimate Edition, you can add the Windows XP Mode to the Windows NT 4.0 domain and connect to Exchange 5.5 server. To get Windows XP Mode, please go to: Download Windows XP Mode 2. Use Microsoft Office Outlook Web Access.

Thanks for the tips - I will test out. One other way I can think of accomplishing this is to have a one-way trust from the NT side to a server running Windows 2008 R2 for example. So people who were logging into the Windows 2008 R2 server would have permissions for the NT server/domain but not the other way around. What are your thoughts on that approach?
