You are the administrator for Contoso, Ltd. You have an Office 365 tenant with Skype for Business Online. You
have an account named Test.User@contoso.com. You configure the account to use the same email address
and Session Initiation Protocol (SIP) address.
You need to change the SIP address for the account to Test.User1@contoso.com.
What should you do?
A.
In the Office 365 admin center, change the display name for Test.User@contoso.com to
Test.User1@contoso.com.
B.
Run the following Windows PowerShell command:Get-MsolUser –UserPrincipalName
Test.User@contoso.com | Set-MsolUser –UserPrincipalName Test.User1@contoso.com
C.
In the Office 365 admin center, add the SMTP address Test.User1@contoso.com to
Test.User@contoso.com
D.
Run the following Windows PowerShell command:Set-MsolUserPrincipalName –UserPrincipalName
Test.User@contoso.com –NewUserPrincipalName Test.User1@contoso.com
Explanation:
The Set-MsolUserPrincipalName cmdlet is used to change the User Principal Name (user ID) of a user.
Example: The following command renames user1@contoso.com to CCole@contoso.com.
Set-MsolUserPrincipalName -UserPrincipalName User1@contoso.com -NewUserPrincipalName
CCole@contoso.comhttps://msdn.microsoft.com/en-us/library/azure/dn194135.aspx
I would answer C
It’s not the upn which is changed but the SIP address which must be the same than SMTP address
What do you think about it ?

SMTP address could be changed only through Exchange AC

D is correct.
I think C should be Exchange Online Admin Center

I would choose C because
1/ you can change a user’s email address from Office 365 admin as shown here
https://support.office.com/en-us/article/Change-a-user-name-and-email-address-in-Office-365-fb5ac074-e203-4e1f-9843-b9d1a3e03297
2/ Set-MsolUserPrincipal changes the user’s UPN AND email address, implying the old email address (Test.User@contoso.com) no longer exists which is not recommended (we should always keep the old email address to prevent NDR unless instructed otherwise)

Agree with Ricky.
D: is correct.
“When a user’s Office 365 sign-in address (also known as the User Principal Name, UPN, or user ID) is changed, the Skype for Business Online (formerly Lync Online) SIP address for the user is automatically synchronized”
https://support.microsoft.com/en-nz/help/2537764/considerations-for-skype-for-business-online-when-you-change-an-office
Set-MsolUserPrincipalName is the command used to change the UPN
https://docs.microsoft.com/en-us/powershell/module/msonline/set-msoluserprincipalname?view=azureadps-1.0
C is wrong because a SIP address is an alias so changing the SMTP (which is the primary email address) would not change the alias. An alias is usually a lowercase smtp.

They do not request to change the UserPrincipalName, they request to change the SIP address, the condition is “You configure the account to use the same email address
and Session Initiation Protocol (SIP) address. “So if the SMTP is changed, the SIP address will be changed when it is synchronized, for me the option is C.
