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

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.
