Using classic Outlook for Windows in business environments
Same issue. Still happening. Now I have to spend twice as much time managing this ****. First, to report it, then to block it. Notice that Google Mail doesn't have this problem.
Also, if you [tech support] don't know the answer to the question that users are posting, DON"T COME BACK WITH SOME UNTESTED BULLSH-T RESPONSES, like "try clearing your cache" and other monkey turd advice that only serves to infuriate intelligent people. I could spit at a brick wall and get a better result.
