- A
Run a playbook that deletes the phishing email from the user's inbox.
Why wrong: Deleting the email does not disable the mailbox or prevent further compromise.
- B
Configure an automation rule to block the sender IP address in Defender for Cloud Apps.
Why wrong: Blocking the sender IP is not directly related to disabling the mailbox.
- C
Run a playbook that resets the user's password.
Why wrong: Resetting password is a different action; the requirement is to disable the mailbox.
- D
Run a playbook that uses the Microsoft 365 Defender connector to disable the mailbox.
The Microsoft 365 Defender connector allows disabling a mailbox as a remediation action.

Automate Mailbox Disablement — Sentinel Playbook for Phishing Incidents
This SC-200 practice question tests your understanding of respond to security incidents. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization has Microsoft Defender XDR enabled. An incident is generated for a user who clicked a phishing link in an email. The analyst needs to automatically disable the user's mailbox for suspicious activity. Which automated action should the analyst configure in a Microsoft Sentinel automation rule?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run a playbook that uses the Microsoft 365 Defender connector to disable the mailbox.
Option D is correct because the goal is to disable the user's mailbox, which is a Microsoft 365 Exchange Online action. A Microsoft Sentinel automation rule can trigger a playbook that uses the Microsoft 365 Defender connector to execute the 'Disable mailbox' action directly against Exchange Online, effectively suspending the user's ability to send or receive email. This aligns with the requirement to automatically respond to a phishing incident by disabling the compromised mailbox.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'disabling the mailbox' with other remediation actions like password reset or email deletion, failing to recognize that only a playbook with the Microsoft 365 Defender connector can directly execute the mailbox disablement action in Exchange Online.
Detailed technical explanation
How to think about this question
The Microsoft 365 Defender connector in Azure Logic Apps (used by Sentinel playbooks) exposes the 'Disable mailbox' operation, which calls the Exchange Online PowerShell cmdlet `Disable-Mailbox` under the hood. This action sets the `RecipientTypeDetails` to `DisabledUser` and removes the mailbox from the user's account, preventing any further email access. In a real-world scenario, this is often combined with a password reset and session revocation to fully contain a compromised account, but the question specifically asks for mailbox disablement.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
