I'm running Win 10 with IE 11 and Outlook 2010. If I click on the links on some emails, I get the message: There was an error decoding this link. Please try the link again, or contact the sender of the email. This seemed to start after a Microsoft Support Engineer helped me get rid of the message "What app do you want to use?" I stopped getting that message, but now I can't open any links on emails from two senders in particular. I contacted one sender and found messages from other users who are having the same problem. No mention of a fix. (Can't remember the name of the other site.) Can anybody help?
