Using Classic Outlook on Windows for personal email, calendar, and contact management
You Rock man!
I had this issue with a very heavy email user and was banging y head on the desk thinking it was a one off issue. I happened to talk to a friend in IT who mentioned they were dealing with a strange outlook issue. It was the same one, once I realized it was happening more wide spread I found your answer here. You saved us so much time and our sanity.
