After I downloaded Windows 10, my Outlook 2010 has a problem. I cannot follow a hyperlink from an email, nor can I 'unsubscribe' from a mailing list. The system advises that I do not have the right level of security. I had this problem over 12 months ago, and I was advised of a program to run to fix the problem. Unfortunately I no longer have this and would appreciate if anyone knows the name of that program.
