Have your company IT dept talk to the client IT dept. - it is most likely a firewall or port issue which they can discuss between them. The client company may not allow a direct or VPN connection to other networks in which case you will be limited to OWA, if your employer has enabled it.

After furious head scratching, AKon asked:

| Hi,
|
| I am currently working at a client location and trying to access my
| organization's Exchange Server through internet. I have configured
| Outlook 2003 for this. But I am unable to access the Exchange Server
| through Outlook. It repeatedly asks for the login credentials and
| does not seem to be doing anything. However, it(access thru internet)
| is working fine when I try from outside the client location, where
| there is a pure internet connection (i.e. w/o firewall) (eg : hotel).
| But there is a firewall at the client location. Not sure if this is
| creating any problems.
|
| Please let me know the settings or how this problem can be resolved.

| Thanks,
