If you create a Scheduled Task and it does not get triggered:
- make sure that Import Manager Scheduling Service is running.
- go to the location where IM is installed (C:\Program Files (x86)\CRM Extensions\Import Manager 8\Scheduling Server\SchedulingServer.exe.config and make sure it is pointing to the right address
<setting name="SchedulingServer_Scheduling_Scheduling" serializeAs="String">
In most of the cases the server address is http://localhost:5544/. In case you will have to change server address in the config file please make sure you restart the service.
