I am having no end of problems getting Exchange 2007 to send and receive through Forefront TMG.I have 1 x Exchange server and 1 X Exchange Edge server (Edge server is on the Domain and not in a DMZ). I have no problems with Internal Email, I have set up OWA and a third party certificate no problem. However I cannot send or receive External Emails.Firstly I tried just creating Access Rules for outbound and InboundSMTP and POP, without success.So I have now used the TMG wizard to publish a Mail server, this is nearly there (I think), asI am now getting authentication errors shown below when I send from hotmailReporting-MTA: dns;snt0-omc3-s17.snt0.hotmail.comReceived-From-MTA: dns;SNT102-W65Arrival-Date: Mon, 23 Mar 2009 14:28:27 -0700Final-Recipient: rfc822;*******.********@*******.comAction: failedStatus: 5.7.1Diagnostic-Code: smtp;530 5.7.1 Client was not authenticatedI presume this is now my Edge Send Connectors and TMG are not set up the same.Can anyone assist? Has anyone got this working ?ThanksJonathan

First of all, this is marked as a comment - not a question. Please select change type and pick question. When Edge and TMG are on the same box, you use the email policy in TMG to configure Exchange. Settings in Exchange will be overwriten by TMG.

Hello, I have some questions regarding your issue(s), - You mean EDGE server is in the domain network, or joined to the domain? - TMG is installed over the EDGE server, or on a standalone Server? - TMG is joined to the Domain or not? - Did you tried to send and receive by bypassing the TMG server (EDGE send and receive to and from internet directly)? what was the result? - where the emails sent externally are queued, on the HUB or the EDGE? - please check the receive connector on the EDGE server, does “Anonymous users” is checked in the "Permission Groups" tab? Waiting your response.
