XCLN: Authentication Credentials Error 554 in Outlook Express

ID: Q186134

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

When Outlook Express users send messages through Microsoft Exchange Server 5.5, the following error message may appear:

An unknown error has occurred.
Subject '<subject>', Account '<sender>', server '<server name>',
Protocol: SMTP, Server Response: '554 Originator address does not match
authentication credentials', Port: 25, Secure(SSL); No, Server
Error:554,
Error Number:0x800CCC6F

Post Office Protocol 3 (POP3) and Internet Message Access Protocol (IMAP) Outlook clients may see the same error message.

The Exchange Internet Mail Service Administrator's inbox may have the following message:

   An Inbound mail message was not accepted on server <server name> because
   the authentication account did not have permission to use the originator
   address on the message. The message that caused this notification was:

      To: <Recipient@name.domain.com>
      From: <sender>@name.domain.com>
      Subject: <subject>

      The submitting host was:
      <Server name.domain.com>

The account used to authenticate the connection was:

\<Sender>

If archiving was enabled at the time of submission, the message can be found in the following file:

<Drive>:\ExchSrvr\Imcdata\In\Archive\W707852B

If the Simple Mail Transfer Protocol (SMTP) protocol log for the Internet Mail Service is enabled, the following message may be present:


   >>> 554 Originator address does not match authentication credentials.

CAUSE

The senders' SMTP e-mail address that is configured in Outlook Express (POP3 or IMAP client) does not match an address in the Exchange directory and cannot be validated by the Internet Mail Service.

RESOLUTION

This resolution assumes the Exchange Administrator wants to retain the anti-spoofing configuration on the Internet Mail Service.

In Outlook Express, ensure the e-mail address entry (from the Tools menu, click Accounts, click the Mail tab, select the User name, click Properties, and then click the General tab) is the same SMTP e-mail address for the Exchange user located in the Exchange directory (under the Exchange user properties, E-mail addresses tab, SMTP address).

MORE INFORMATION

If you are using Netscape Communicator 4.03, the following dialog box will be displayed:

An Error occurred sending mail.

The mail server responded: Originator address does not match
authentication credential.

Please check the message and try again.

Refer to Netscape documentation for proper configuration.
