Troubleshooting Microsoft Exchange Online — Question 29

A company uses Exchange Online.
A user receives a non-delivery report when sending emails to external recipients. You perform a message trace and discover that emails are not being sent from the Exchange environment.
You need to identify the component that is causing the issue.
Which component is causing the issue?

Answer options

• A. Anti-spoofing protection
• B. Connection filter policies
• C. Anti-phishing protection
• D. Mail flow rules

Correct answer: D

Explanation

The correct answer is D, Mail flow rules, as they can block or redirect emails based on specified conditions, which can lead to non-delivery reports. The other options, such as Anti-spoofing protection, Connection filter policies, and Anti-phishing protection, primarily focus on security measures and do not directly control the flow of outgoing emails in the same way.
