SYMPTOMS
When you try to send an e-mail message to a recipient that is located in your Microsoft Exchange organization, you may receive a non-delivery report (NDR) message that is similar to the following:

Your message did not reach some or all of the intended recipients.

Subject:

Sent:

The following recipient(s) could not be reached:

on

Unable to relay for



CAUSE
This behavior may occur when you configure more than one e-mail account in Microsoft Office Outlook 2007 or in Microsoft Office Outlook 2003. When you configure more than one e-mail account in Outlook, the default e-mail account is always used to send your e-mail message. If the default e-mail account cannot deliver the e-mail message, you will receive an NDR. If you do not want to use the default e-mail account when you send an e-mail message in Outlook, you must specify the e-mail account that you want to use to send the e-mail message.

For example, if you configure a Simple Mail Transfer Protocol (SMTP)/Post Office Protocol (POP) e-mail account as the default e-mail account in Outlook and then configure a Microsoft Exchange Server e-mail account in Outlook, your POP3 e-mail account, not your Exchange Server e-mail account, is used to send the e-mail message when you send an e-mail message to an internal recipient in your Exchange organization.



RESOLUTION
To resolve this behavior, use one of the following methods.

Method 1: Specify the e-mail account that you want to use to send your e-mail message
To specify the e-mail account that you want to use to send your e-mail message, follow these steps:
 * 1) Start Outlook, and then click New (Mail Message).
 * 2) Click Accounts, and then click the e-mail account that you want to use to send the e-mail message. For example, if you want to send the e-mail message with your Exchange Server e-mail account, click Microsoft Exchange Server.

Method 2: Make the Exchange Server e-mail account the default e-mail account in Outlook 2003
To make the Exchange Server e-mail account the default e-mail account in Outlook 2003, follow these steps.

Note You do not need to use method 2 for Outlook 2007.
 * 1) Start Outlook 2003.
 * 2) On the Tools menu, click E-mail Accounts.
 * 3) In the E-mail accounts wizard, click View or change existing e-mail accounts, and then click Next.
 * 4) In the list of e-mail accounts, click Microsoft Exchange Server, and then click Set as default.
 * 5) Click Finish to close the E-mail accounts wizard.

Note By default, Microsoft Exchange Server 2003 does not relay e-mail messages. Therefore, if you set your Exchange Server as your default e-mail account, you may receive an NDR from your Exchange Server if you try to send an e-mail message to a recipient that is external to your Exchange organization or if you do not specify another e-mail account to use to send the e-mail message.



MORE INFORMATION
When you configured multiple e-mail accounts in Microsoft Outlook 2002, the e-mail message may have be sent by another e-mail account if the e-mail message could not be delivered by the default e-mail account. This behavior has changed in Outlook.

In Outlook 2007 and in Outlook 2003, you can select the e-mail account that you want to use to send an e-mail message. If you do not select an e-mail account to send an e-mail message, the default e-mail account tries to send the e-mail message. If the e-mail message cannot be delivered by the default e-mail account, the e-mail message is not sent by another e-mail account. This change in behavior increases your control of the e-mail account that is used to deliver e-mail messages, and it helps to make sure that e-mail messages are sent by the e-mail account that you want to use. In Outlook 2002, Microsoft Outlook automatically selects a different e-mail account if an e-mail message cannot be sent by the default e-mail account.

For example, if you want to send an e-mail message to an internal recipient from your Exchange Sever e-mail account, but you have a POP3 e-mail account configured as the default e-mail account, and you did not specify to use your Microsoft Exchange Server e-mail account, you receive an NDR if the POP3 e-mail account cannot deliver the e-mail message. The e-mail message is not sent automatically by your Exchange Server e-mail account.
