I represent marketing team. Leads are either manually entered or imported directly from the website. Based on the Lead I will assign it to the respective Sales colleague. The problem starts here, Once the lead is assigned I am not able to view the Lead from my login. 

If I am not able to view, I will not be able to track the lead progress or update any extra information regarding the lead. Please help me how to overcome this situation. I am an Enterprise edition user of Zoho.
