Question #5
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have a Microsoft Exchange Online tenant that contains 1,000 users. A user named User1 receives a non-delivery report (NDR) when attempting to send an email message to an internal group named sales@contoso.com. The NDR contains the following text: “5.7.1 Delivery not authorized.” You need to ensure that User1 can send email to sales@contoso.com successfully. Solution: You modify the properties of the sales@contoso.com group.
Correct answer: A
Explanation
The 5.7.1 Delivery not authorized NDR occurs when the group only accepts messages from authorized senders. Modifying the group's delivery management settings to allow User1 (or all senders) fixes the problem, so the goal is met.
