The Task Communications Management plugin (com.snc.task_communication_management) is activated when you activate the Incident Communications Management plugin (com.snc.iam) or the Incident Management - Major Incident Management plugin (com.snc.incident.mim). This plugin includes demo data and activates related plugins if they are not already active.

1. Navigate to System Applications > All Available Applications > All.
2. Find the plugin using the filter criteria and search bar.

   You can search for the plugin by its name or ID. If you cannot find a plugin, you may have to request it from ServiceNow personnel. To request a plugin, follow the steps in Request a plugin.

3. Click Install, and then in the Activate Plugin dialog box, click Activate.
   Note: When domain separation and delegated admin are enabled in an instance, the administrative user must be in the global domain. Otherwise they will receive the following error: Application installation is unavailable because another operation is running: Plugin Activation for <plugin name>.
