Microsoft 365 Messaging — Question 62
Your network contains an Active Directory domain. The domain contains an on-premises Microsoft Exchange Server 2019 organization.
You have a hybrid deployment between the Exchange Server organization and an Exchange Online tenant. Exchange Online contains all the mailboxes, including a shared mailbox named CustomerSupport.
You need to ensure that users cannot directly sign in to the CustomerSupport mailbox. Shared mailbox functionality must be unaffected.
What should you do?
Answer options
- A. Remove the user account of CustomerSupport from Active Directory.
- B. From the Microsoft 365 admin center, block sign-ins for the user account of CustomerSupport.
- C. Remove the user account of CustomerSupport from Azure AD.
- D. From the Microsoft 365 admin center, reset the password for the user account of CustomerSupport.
Correct answer: B
Explanation
The correct option is B because blocking sign-ins for the CustomerSupport user account in the Microsoft 365 admin center prevents users from directly accessing the mailbox while preserving its shared mailbox functionality. Option A is incorrect as removing the account from Active Directory would eliminate its associated mailbox. Option C is also wrong for the same reason, as deleting the account from Azure AD would disrupt mailbox access. Option D would not prevent sign-ins, as resetting the password would still allow users to access the mailbox.
