Cant login from internet using POP3 Clients

[ahsanmir]

i am trying to connect to my Exchange 5.5 server with IMS connector from the internet using a outlook express. The client machine doesnot dial into the server. i am just trying to see if its possible to connect the client in such a condition. I am not using SSL or anyother Encryption at the moment. These are the 2 error messages that i am getting in my Outlook express.

Exchange 5.5 will authenticate you against either an Active Directory account (if your Exchange server is a member of a Win2K domain), an NT domain account (if you don't have a 'native' AD environment) or a local user account (created in the accounts database on the local Exchange server.

Are you using the user name, or the mailbox name when you connect? Are they the same? If you are running an AD environment, you should be able to use the full email address as your login name, ie "shack@networkdesigner.net" or something like that and supply your domain password.

If you've looked carefully at all the authentication variables and are still having trouble, you should turn on detailed logging in the Internet Mail Service to show SMTP Interface Events and SMTP Protocol Log to see if it gives you any clues about what's happening. You can also turn auditing on for logons at the server level and see what shows up in your security log.

Oh, and why does the error message list your IP address as the account name? You should be putting the user account name there. Look in your Outlook Express settings and see where it was that you put the IP address where it shouldn't be.

I just fixed this problem on my Outlook client. When you give the user name and password do so in the following maner:

User: <Domain Name>/<user name>/<mail box>
Password: <password>

It seems a little crazy but I tried this after verifing my connection with telnet (this is how you login to a pop3 server using telnet) and it also works from Outlook and Outlook Express.

Good luck
