When you first log in to your system, it is defaulted to show only the In Progress Enquiries that are assigned to you as a user 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 top left corner - it is likely to be displayed as ‘Assigned to me’ by default, but if you then click on this it will give you the option to change this to ‘Assign to Anyone’
