  2. Click +Add Hub at the top of the dashboard. Choose the type of object you want to sync of the Hub Setup Wizard will appear.
    NOTE: CiraHub can also sync object types with different  data sources. For example, syncing the calendar events in the main calendars folder of your mailbox with a Public Folder Calendar. If you want to sync your calendar events to another data source, click +Add Spoke in the appropriate Hub.
