Exchange 2007 will not accept Client email outbound using OWA
Posted on 2007-11-26
Using an SMTP server, Hub Transport Server and Mailbox Server, Exchange 2007 will not send outgoing email. Using OWA the Hub Transport Server produces an NDR #530 5.7.1 User not Authenticated, yet the Default Receive connector has the correct permissions and is in the annonymous group. Any ideas? I am lost on this one. This is a new install, so everything should work out of the box...unfortunately this is Microsoft. How do I properly setup the connectors to allow authenticated users to send outgoing email?
