I am currently running Exchange 5.5 SP4 on Windows NT 4.0 SP6a. I have an Outlook 2000 client running on Windows 2000 SP2, that cannot receive any e-mail messages from just one client, which is also Outlook 2000 running on Windows ME. I can recieve e-mails from everyone else. Also the outlook client on WinME can receive e-mail from the outlook client on Win2K. I have reinstalled both clients, and still have the same problem. Please help.
