Windows 7/Office 2007. I just installed Office 2007 on a brand new HP Laptop running W7 64bit. When click on a URL in an email, I get the following error message, "MICROSOFT OFFICE OUTLOOK. This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator". This also happened when clicking on an "Unsubscribe" link in a different email. Can someone please tell me how to resolve this issue? Thanks in advance.
