Webmail working for local users but not for users outside network


Dear Friends,

I am stuck up with major problem.

We are running Exchange server 2000 and using to operate Mailboxes for our company and also for our clients. Problem is as below:

Say our domain name is our-domain.com and email accounts happens to be
employee1@our-domain.com and so on.

Also we have email accounts for clients say "client1@client-domain.com" and so on.

I can access and for that matter everybody in our office can access webmail but our clients can not access webmail from their computers (Accessing from different location). I also tried to connect locally with one of our client's account and I too can not conect..

Now I don't understand what settings I have to do with IIS 5.0.. I checked the permissions through "Active Users and Computers" for each user and all have same settings.

Please help

Explain where the OWA server is located.

Is it on the E2K server on the LAN or in a DMZ?

Are you using HTTP or HTTPS?

Are you using a Firewall to NAT HTTP or HTTPS if it is running on the LAN on the same server as E2K?

Do your clients connect using a VPN?

What errors are in your event logs?

A lot more info would be helpful...

Hi Mfay and Vahik,

Thank you for responding..

My problem is solved.. Actually I had to add additional SMTP address in each user account as client1@our-domain.com and it worked.

Thank you all for your support..
