When you create a custom entity in Microsoft Dynamics CRM, it is automatically assigned a default icon, and all custom entities by default use the same icon. If you create multiple custom entities, it can be useful to change the icon associated with one or more custom entities to help users differentiate between them.
In order to change the entity icon, you will need to have CRM administrator security access. Here are the steps to do it.
How to Change a Custom Entity Icon

Click on Customize the System
Within the default solution, expand the Entities folder and locate the custom entity you want to update the icon for.
Click on the Entity name to gain access to the entity properties
In the Ribbon, click on the button called Update Icons

Close the window
In the look up record window, Click Add.
Repeat steps 6-15 to create your 32×32 pixel web resource
