Understanding NDR Files in Outlook

What is an NDR File?

An NDR file is generated by an email server when it fails to deliver a message. This report details why the email could not be sent successfully, often including the recipient’s address and the specific error code.

When Do You Encounter NDR Files?

Typically, you receive NDR files when:

  • The recipient’s email address is incorrect or non-existent.
  • The recipient’s inbox is full.
  • There are restrictions on the recipient’s email server.

Step 1: Locate the NDR File

Start by checking your email inbox or the folder where you store delivery reports. Look for messages labeled as “Undeliverable,” “Delivery Failure,” or similar. The NDR file may be included as an attachment.

Step 2: Open the NDR File

  1. Double-click on the NDR attachment.
  2. Outlook should automatically recognize the file format and open it, displaying the details of the delivery failure.

Step 3: Review the NDR Content

  • The reason for the failure (e.g., “Mailbox Not Found”).
  • The email address of the intended recipient.
  • Error codes that may assist in troubleshooting.
