MB-910 Describe Dynamics 365 Customer Service Practice Question
A support team is using Dynamics 365 Customer Service to manage cases. They notice that when a customer replies to an email, a new case is created instead of updating the existing one. What is the most likely cause?
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
✓
The queue's 'Update existing case based on email subject' setting is disabled
The Email-to-Case queue's advanced settings need to have 'Update existing case based on email subject' enabled to automatically associate replies with existing cases. Option A is wrong because the conversion rule controls how emails become cases, but not the specific update behavior. Option C is wrong because email templates are for outgoing emails. Option D is wrong because the entitlement defines support coverage, not case updates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The customer's entitlement is expired
Why it's wrong here
Expired entitlements affect support eligibility but not case creation from emails.
- ✓
The queue's 'Update existing case based on email subject' setting is disabled
Why this is correct
Enabling this setting allows replies with matching subject lines to update existing cases.
- ✗
The email-to-case conversion rule is misconfigured
Why it's wrong here
The conversion rule defines how emails become cases, but not whether replies update existing cases.
- ✗
The email template is not set to link to the case
Why it's wrong here
Email templates are for composing outgoing emails, not for incoming email processing.
