Device unable to connect to exchange server

I have a device that will not connect to the exchange SMTP server. All other accounts work fine and the device will connect to a SMTP set up on a laptop (IIS). I can take the same configuration information and use it on another machine with no problem. If the device can send mail through the laptop, that should prove that mail is being formed and transmitted correctly, right? If so, what could be causing the server to reject connection to the device? BTW, customer won't let me on the server and I can't Telnet in.

Thanks. We'll let you know when a new response is added.

Some times the devices won’t authenticate with the server, do check the authentication settings, if possible use the IP address of the server for SMTP settings and check.

    Also, please provide more information as to the environment you're connecting through. The the laptop physically on the same subnet or network segmen as the Exchange server? Are you connecitng through VPN or PPTP? Are there any workstation-based firewalls on this laption that would prevent connections through port 25 (or 80 / 443 if connecting through RPC Over HTTP)? You also ask "If the device can send mail through the laptop, that should prove that mail is being formed and transmitted correctly, right?". Does this mean you've gotten the device to connect and successfully send email? There's a lot of environmental issues (like Exchange version (from Technochic) that you haven't discussed that could all play a part. Can the same laptop connect to and work properly with other POP/SMTP servers (like external email accounts)?

    Sorry, should have included this info. 2003, SP2 The device (Xerox MFP) is on the same subnet. No VPN or firewalls inside the LAN. I can set up an SMTP server on my laptop and the mail will successfully deliver, so that rules out an issue with the machine. I have not tried using another external SMTP server. I can put the same settings in another Xerox and successfully deliver through the customer's server so that means authentication, etc. is correct. The customer states that his logs show no authentication errors (or errors of any other type for that matter). The Xerox will only show that the server does not respond.

    If you cannot telnet to the Exchange server then either it is not running an SMTP listening connector or it is rejecting connections from your subnet. Check the connectors on the Exchange server and see if they are active and listening for connections from the subnet where your client is located. The next thing to check as suggested is if there is any authentication required. One other item to look at is if the Exchange server is only looking for TLS (secured) connections.
