Installed MS proxy and configured Exchange to work with it. Internal clients can send and recieve mail to eachother and to and from internet. In addition, remote clients can log on and send and receive via POP3 and SMTP using Outlook 2000s internet mail client, but they can’t use outlook 2000 to log on using the exchange server (which relies on MAPI for functionality). Everyone recieves the enter password screen and no one can log on to it!
The error message is “the logon credentials supplied were incorrect”, but they are correct! So the data is getting through to the server, and its rejecting it. in addition, i can telnet to MS Proxy and logon to the POP3 service successfully. Do I have to tweak MAPI somehow? What ports does MAPIuse? I haven’t found much at all online about MAPI. Why can’t anyone outside authenticate? All the ports are open. It doesn’t sound like a proxy problem to me, but please enlighten me.
Thanks in advance.
