Hello, I am experiencing quite a few issues trying to set up my new Exchange servers Here my conf : 1 exchange cluster with 2 servers : Exch1 & Exch2 (2010 fully updated) 1 TMG 2010 that also run the Edge service (2010 fully updated) ---------------------- I am able to logon to OWA, send and receive internal emails without any issues. The Edge files have been generated on the TMG and placed onto both Exchange But when I tried to send or receive an email from External not working. My MX is well redirected to my TMG external IP address When I send an email (external) to an internal mailbox, the email stay stuck into the edge server (I can see it into the QUEUE Viewer) (Last error Message 451.4.4.0 DNS Query failed) When I send an email (Internal) here the delivery report The message has been queued on server 'xxxx-exch2.xxx.lan' since 23/02/2011 19:57:22 (UTC+01:00) Brussels, Copenhagen, Madrid, Paris. The last attempt to send the message was at 23/02/2011 19:53:02 (UTC+01:00) Brussels, Copenhagen, Madrid, Paris and generated the error '451 4.4.0 Primary target IP address responded with: "421 4.2.1 Unable to connect." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts.'. In my edge I am not sure what to put into my RECEIVE/SEND connector, what type of authentication... Same for the parameter into TMG, I did use the Wizzard to create both internal and External rules, but I didn't find anywhere to refer to to check if my config was ok (TLS, base, integrate,...) and last issue, when I do the Start Edgesynch one of the servers report success (Exch1), the other cannot connect. same conf for both so no idea why. Looking for help :) Thanks

wow, you made me zoom in for this one! 5.5 font size, huh? you need to ensure the edge server can resolve your internal servers. you also need the edge server's dns suffix before you install the edge role. did you do this? don't adjust the connectors. edgesync takes care of the necessary configuration, or i should say TMG does in your case (it uses edgesync).

Thanks for your answer but can you explain the second part a little, My Edge server can resolve the Edge (when I tracert the servers it get the correct IP) But what about the Edge server DNS suffix, what am I to do with that ? Thanks

"This topic explains how to configure a Domain Name System (DNS) suffix on a computer on which you will install the Microsoft Exchange Server 2007 Edge Transport server role. Before you install the Edge Transport server role, you must configure a DNS suffix for the server name. After you install the Edge Transport server role, you must not change the server name. Modification of the server name after you have installed Exchange 2007 is not supported." 2007: http://technet.microsoft.com/en-us/library/bb123528(EXCHG.80).aspx 2010: http://technet.microsoft.com/en-us/library/bb123528(EXCHG.140).aspx Mike Crowley Check out My Blog!
