The super administrator can  disable all users who is a member of Office 365 tenant by using this application. The application is a web page which has a button for disabling or allowing users. A user must log in to Office 365. If authorized user is a member of Office 365 tenant and he is a member of special security group then he will be able to disable all users. Only a super user can allow users. Nobody can disable the super user. He can only allow users. The application uses Azure Active Directory Graph for working with Office 365. The application is deployed to Azure and is dublicated to different data centers for accessibility. Also we have an option to install application to different CMS, but it will lack a function of blocking Active Directory Access (but will still block outlook web access, e-mail services and ActiveSync).
