Answer: B

Explanation:

We can use the Set-Mailbox cmdlet with the EmailAddresses parameter to configure the email addresses foruser’s mailbox. In this question, we need to modify the Lync address. Lync addresses are notated by placing SIP: in front of the address whereas Exchange email addresses are notated by placing SMTP: in front of the address.

In the PowerShell script:

The$ID variable is used to store the users identity.

The $OldAddress variable is used to store the users old Lync address SIP:[email protected].

The $NewAddress variable is used to store the users new Lync address SIP:[email protected].

In the following PowerShell command:

Set-Mailbox -Identity $ID -EmailAddresses@{add = "$NewAddress"; remove = "$Old Address"}

The EmailAddresses parameter adds the new address by (add = "$NewAddress") and removes the old address (remove = "$Old Address") thus changing the Lync address as required in the question.
