Active Sync adapters can be disabled, manually started, or automatically started. You must have the appropriate administrator capability to change Active Sync resources in order to start or stop Active Sync adapters. For information about administrator capabilities, see Capabilities Categories.
When an adapter is set to automatic, the adapter restarts when the application server does. When you start an adapter, it will run immediately and execute at the specified polling interval. When you stop an adapter, the next time the adapter checks for the stop flag, it will stop.
