I have Exchange server 2003 running atop Windows Server 2003. Road warriors
running outlook express 6.0 can relay mail, but not those using Outlook
2003 - isn't that very strange? Why is it that Outlook 2003, a much
advanced email client, is unable to relay, while a simple minded system such
as OE6 can relay without the slightest problem?

One thing I do note that's different on OE6 is that it asks the user to
authenticate when sending email with a dialog that requests for username,
password and domain. Outlook 2003 does not have the domain part. So, in my
infinite wisdom, I tried entering the username in the Outgoing server dialog
as username@domain to no avail!

Summary:
- Internal users can send to both internal and external recipients
irrespective of email client in use.

- External users can send to both internal and external recipients only when
using OE6.

- External users can send only to internal users when using Outlook 2003.

- All users can send vi the OWA portal.

These are the only clients we use in our organization.



Please, please, can someone come to my rescue!!!

Never mind, 'twas just another brain fart - been having plenty of those
lately!
