Looks like Paresh has a Customer profile on CCO based on the /customer in the URL of the posted link. Your CCO profile might be something other than Customer such as Partner and this is why your are denied access to his links.
Just removing "customer" from the link will produce an invalid link and not solve the problem. For many of the pages reached through customer there are also versions of the page reached through public. You might try replacing customer with public and see if that works.
