You are the administrator for Contoso, Ltd. You have an Office 365 tenant with Skype for Business Online. You
have an account named [email protected]. 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 [email protected].
What should you do?
A.
In the Office 365 admin center, change the display name for [email protected] to
[email protected].
B.
Run the following Windows PowerShell command:Get-MsolUser –UserPrincipalName
[email protected] | Set-MsolUser –UserPrincipalName [email protected]
C.
In the Office 365 admin center, add the SMTP address [email protected] to
[email protected]
D.
Run the following Windows PowerShell command:Set-MsolUserPrincipalName –UserPrincipalName
[email protected] –NewUserPrincipalName [email protected]
Explanation:
The Set-MsolUserPrincipalName cmdlet is used to change the User Principal Name (user ID) of a user.
Example: The following command renames [email protected] to [email protected].
Set-MsolUserPrincipalName -UserPrincipalName [email protected] -NewUserPrincipalName
[email protected]https://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 ([email protected]) 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.
