Why have I had "Access Denied " to links included in email received from a govt dept.  This is the first time this has happened on my home computer or for that matter any email attachment at work or at home.  Message is as below:  

"
  • Access Denied by security policy

The security policy for your network prevents your request from being allowed at this time. Please contact your administrator if you feel this is incorrect."


Can you please advise?  I have to see these links for a project I'm doing.
