By default, non-administrative users are unable to see any leads in any LeadGroups unless specifically granted access to one by an administrator. If a non-admin user is not granted access and tries to create a lead, they will be logged out of the system when they try to add a new lead.
To correct this, an administrator will need to go to the “Workflow” tab. From there, they will then need to click on the “LeadGroups” link.
The admin will then need to find the LeadGroup(s) they wish the user to have access to and check the box(es) to the left of its name(s). From there, they will need to scroll down and find the user’s name in the “User List” and highlight that name. Once they click the “Submit” button, the user will have access to the LeadGroup(s) selected.
The user will need to log out and back for the changes to take, but once they do, they will then be able to create new leads in the system.
