Microsoft 365 Administrator Expert MS-102 Practice Question

A user in your Microsoft 365 tenant was automatically added to the Restricted users list after the account sent a large volume of outbound spam. You have verified that the account is now secure and you need to restore the user's ability to send email outside the organization as soon as possible while keeping the incident history for future review.

Which action should you perform in the Microsoft 365 Defender portal?

  • Add the user's address to the Tenant Allow/Block List as an allowed sender.

  • In Email & collaboration > Review > Restricted entities > Users, select the account and choose Unblock user.

  • Run the Set-Mailbox cmdlet in Exchange Online PowerShell and set the ExternalEmailEnabled parameter to True.

  • Wait until the 30-day automatic expiry period removes the user from the list.
