I am using Outlook 10 with Windows 10. It has been working fine until today. I got two emails with interactive buttons to click. One, from my dentist, asked me to click on a button to confirm my appointment, and another from a woodworking site refused to open a video when I clicked on it. In each case I got this error message: "This operation has been canceled due to restrictions in effect on this computer." It told me to contact system administration, but this is my home computer. I haven't done anything in the way of blocking stuff since yesterday, when it was working fine. When I joined this website a few minutes ago, I got the confirmation email and clicked on the web address. I got the same error message, but when I returned to this website it said I had confirmed, so apparently despite the error message it got through. However, I still can't watch my video. I have run the repair function on Microsoft office 10, and still nothing. What is blocking responding to buttons? Thank you.
