When you first log in to your system, it is defaulted to show only the In Progress Enquiries that you are assigned to and any New Enquiries in the system.

You can change this so you can view all enquiries in the system - this function is located on your Enquiry page in the Left panel - it is likely to be displaying as ‘Assigned to me’ > if you then click on this it will give you the option to change this to ‘Assign to Anyone’
