This app helps you to manage your Windows Small Business Server 2011 Essentials from your phone. You can also store multiple server accounts within this app in case you want to manage multiple servers. You must install the “Windows Server Solutions Phone Connector” add-in on your Windows Small Business Server 2011 Essentials in order for your Windows Phone to connect to the server. You can download the free server add-in from Microsoft.com/downloads. Before installing the add-in on the server, confirm that it is not already pre-installed on it.
