You can change the name associated with an System Center Advisor user but not the Microsoft account associated with that user. You can also change your notification settings.
To change user information
On the Account page, in the User Information section, enter the name in the First name and Last name fields.
Change your notification settings. By default, all account users are notified when an alert is generated. To stop receiving these notifications, clear the Receive email notifications of new Advisor alerts option.
