Configuring Package Subscriptions
Configure subscriptions and subscription templates to allow the device user to be notified when information is available, depending on the subscription properties configured for a package. Subscription templates allow you to configure predefined properties for a synchronization group. A client's first synchronization for a specified synchronization group results in subscription creation using both the template and client-specified properties.
Managing Subscriptions
Manage subscriptions to control the messages that application connections receive.
