Explanation:
The Set-MsolUserPrincipalName cmdlet is used to change the User Principal Name (user ID) of a
user. This cmdlet can be used to move a user between a federated and standard domain, which will
result in their authentication type changing to that of the target domain.
The following command renames user1@contoso.com to CCole@contoso.com.
Set-MsolUserPrincipalName -UserPrincipalName User1@contoso.com -NewUserPrincipalName
CCole@contoso.com
