Dear All, Please I am receiving an authentication error. after I have typed the alias name, the system gives me an error message of page cannot be displayed. Please kindly what do I need to do in order to change this? If I user the exchange administrator username and password I go through to the mailbox but I cannot use a particular user account. The OWA is installed on another box (member server) as opposed the exchange server. I am running Exchange 5.5 and Windows NT 4.0 Regards DISCLAIMER: This message and any attachments are confidential and may be legally privileged or otherwise protected from disclosure.
