Double-click the Organization Browser Support Message resource to open it. You will be presented with the dialog below. Edit the highlighted tokens to change the Organization Name and Administrator Name to the respective values for your CRM organization.
Step4: If you have users (such as any developers) that will need to access your CRM organization in a browser other than IE, you can open up their User record in CRM and give them the “Any Browser Allowed” security role. This will enable that user to browse to your CRM organization using any supported browser.
