This video demonstrates how to enable, view and delete account delegates for a business account in the Microsoft Account portal.
Account delegates have full access to your account; however, they cannot add, remove, or view other account delegates. You can configure up to 10 account delegates.
The account delegate does not gain access to the information in the Microsoft Azure Management Portal. Account Delegates are different from Co-administrators.
The Microsoft Azure Account Center currently does not display when a user is logged on as an account delegate. It is up to you to administer account delegates in the Microsoft Account portal.
