You support Microsoft Lync Server 2013 servers in your customer’s company network. The network
includes an Active Directory Domain Services (AD DS) domain and an Exchange 2010 organization.
The company deployed a pilot Microsoft Exchange 2013 installation at one of its branches and
moved the branch users’ mailboxes to Exchange 2013. Lync users from the branch were configured
to use the Unified Contact Store. Due to budget limitations, the company has decided to move the
users’ mailboxes back to Exchange 2010. Before you move the users’ mailboxes, you need to change
the users’ properties. Which two actions should you perform? (Each correct answer presents part of
the solution. Choose two.)

A.
Run the Test-CsUnifiedContactStore cmdlet once.

B.
Run the Move-CsUser cmdlet for every user account.

C.
Run the Invoke-CsUcsRollback cmdlet for every migrated user account.

D.
Run the Set-CsUserServicesPolicy cmdlet once.
