I have an Exchange 2003 Server.  One of my users (only one that I can tell so far) has an issue sending mail to anyone else on the server.  She gets the following error:

"The message could not be delivered because the recipients destination email system is unknown or invalid.  Please check the address and try again, or contact your system administrator to verify connectivity to the email system of the recipient"

<WIMAD-EXCHANGE.wi.loc #5.1.2>


Have searched on the web but cannot find the same issue.  Can anyone help?

Figured out answer myself- it was due to Outlook 2003 caching.  Have no idea why but turning it off worked.

I know I must seem like an idiot, but I cannot find a way to e-mail anyone that handles the site.
