SC-200 Practice Question: Uses Microsoft 365 Defender and receives an alert…
An organization uses Microsoft 365 Defender and receives an alert for a suspicious email sent to multiple recipients. The analyst wants to view the email metadata, including the sender, subject, and any attachments. Which advanced hunting table should the analyst use?
⚠ Common exam trap
A common mix-up: candidates confuse the purpose of EmailAttachmentInfo (which only has attachment metadata) with EmailEvents (which has the full email header), or they mistakenly choose DeviceEmailEvents thinking it covers all email activity, when it only logs client-side email events on endpoints.

Correct answer & explanation
✓
EmailEvents
The EmailEvents table in Advanced Hunting stores the core metadata for every email processed by Microsoft Defender for Office 365, including sender, subject, recipient, and delivery status. Since the analyst needs to view the sender, subject, and attachments for a suspicious email sent to multiple recipients, EmailEvents is the correct starting point because it contains the primary email envelope information.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
EmailEvents
Why this is correct
EmailEvents is the central advanced hunting table in Microsoft 365 Defender for email message-level data within Exchange Online. It exposes fields such as SenderFromAddress, SenderDisplayName, RecipientEmailAddress, Subject, and EmailDirection, as well as the delivery action (e.g., Delivered, Junked, Blocked, Failed) via the DeliveryAction column. For any scenario requiring the identity of the sender, the subject, or the final disposition of an email, EmailEvents is the correct table to query first.
- ✗
EmailAttachmentInfo
Why it's wrong here
EmailAttachmentInfo is scoped specifically to attachment-level attributes, including AttachmentName, SHA256, FileSize, and the threat detection verdict for each file attached to a message. This table does not include sender, recipient, or subject fields because those belong to the parent message and live in the EmailEvents table. To correlate a suspicious attachment with its email metadata, you must join EmailAttachmentInfo to EmailEvents using the NetworkMessageId field, so relying on this table alone would miss the required sender and subject information.
- ✗
EmailUrlInfo
Why it's wrong here
EmailUrlInfo is an advanced hunting table that focuses exclusively on URL-related data extracted from email bodies and on user click activity, including fields like Url, UrlLocation, and ClickAction. It does not contain the core message attributes such as the sender address, subject line, recipient list, or delivery disposition because those are stored at the message level in EmailEvents. Thus, while EmailUrlInfo is valuable for investigating phishing link clicks, it cannot by itself answer a query about email metadata like sender or subject.
- ✗
DeviceEmailEvents
Why it's wrong here
DeviceEmailEvents is not a real advanced hunting table in the Microsoft 365 Defender schema; the schema only includes EmailEvents, EmailAttachmentInfo, and EmailUrlInfo for email-related investigations. The similarly named DeviceEvents table exists, but it records endpoint operating system events such as process creation, file creation, and registry modifications, not email messages. Attempting to query DeviceEmailEvents would result in a KQL 'table not found' error, making it impossible to retrieve any email metadata from this option.
