You receive a "No transport provider was available for delivery to this recipient" error message when you try to send an e-mail message in Outlook 2000

When you send a mail message, you may receive an undeliverable message from the system administrator. The error in the body of the message is: This is commonly referred to as an non-delivery Report (NDR).

There are several reasons for this error message. They include:

• A damaged Personal folder.
• The installation of Microsoft Outlook Express is damaged.
• Outlook Express has been removed.
• No mail transport service in the mail profile.
• Improperly configured mail transport in the mail profile.
• A damaged contact within a distribution list.
• A damaged contact.
• An apostrophe in your computer name.
• The mail server is expecting the addresses to be enclosed in angle (<>) brackets.
• The mail server doesn't recognize your IP address.
• The POP3 enabled Microsoft Exchange Server you are connecting to is not properly configured for Secure Socket Layer (SSL) authentication.
• No Delivery or Address Type for Microsoft Mail Service

To determine which of these causes is producing the error message in your case, see the troubleshooting articles in the "More Information" section.

Make sure that Outlook Express is installed and working correctly if you send mail through the Internet e-mail service in the Corporate or Workgroup installation, or the Internet Mail Only installation.

A Damaged Contact Within a Distribution List

A damaged contact within a distribution list (DL) can create an NDR when sending an e-mail message to a distribution list. To find the damaged contact, you will need to send a series of test messages with small groups (1/2) of the original distribution list. Once you receive the NDR, you can then narrow the group and eventually isolate the damaged contact. The damaged contact will need to be deleted and re-created (see the following section for creating a new contact.)

A Damaged Contact

To delete and re-create the contact, follow these steps:

1. In the Contact folder, click to select the damaged contact.
2. On the Edit menu, click Delete, or press CTRL+D.
3. On the Actions menu, click New Contact.
4. Enter the information into the Contact form, and then click Save and Close.

An Apostrophe in Your Computer Name

To remove the apostrophe from your computer name, follow these steps:

1. In Control Panel, double-click the Network icon.
2. On the Identification tab, type a new name for your computer without the apostrophe.
3. Click OK, and then restart your computer.

Mail Server Expects Addresses to Be in Angle Brackets

Some SMTP servers require that addresses be enclosed in angle brackets. This is particularly true for older mail server systems. In addition, your e-mail name, which is defined in the Internet e-mail information service properties, must also be enclosed in angle brackets.

For example, the e-mail addresses should have this format:

Check with your Internet Service Provider (ISP) for their addressing requirements. For other people with newer servers to be able to reply to your messages, you must type your e-mail name in the Reply Name box without angle brackets.

Unrecognized IP Address

This can occur if you connect to the Internet using one service provider (ISP), and attempt to send e-mail through a different ISP's mail server. The error is an attempt to prevent the sending of junk mail (SPAM). The only solution is to send e-mail using the mail server of the active connection.

Improperly Configured Microsoft Exchange Server POP Service

The referenced error may occur if the Microsoft Exchange Server is not properly configured to use Secure Socket Layer (SSL) authentication.

No Delivery or Address Type for Microsoft Mail Service

2. Click Start, point to Settings, and then click Control Panel.
