Your company has a hybrid deployment Office 365. You create a user in Office 365. The next day,
you discover that the new user account fails to appear in the Microsoft Exchange Server onpremises global address list (GAL).
You need to ensure that the user has a mailbox and appears in the Exchange on- premises GAL and
the Office 365 GAL.
What should you do?

Assign a Microsoft Exchange Online license to the user account.

B.
From the Microsoft Online Services Directory Synchronization tool, enable rich coexistence.

C.
From the Office 365 portal, modify the sign-in status of the user account.

Delete the user account hosted on Office 365. From the Exchange Management Console, create a
new remote mailbox.
