I'm running Office 2010 and using Outlook for email. Everything was working fine until some automatic updates were downloaded to my computer. Ever since then, whenever I click on a link in an email, it no longer opens and I get an error message saying: "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator." Since this is my home computer, that would be me. I've explored different settings under default programs and Help/Options/Trust Center but so far nothing solves the problem.
