Well, something happened that triggered my Exchange Online account / Office365 account to switch Clutter BACK off despite only switching it back on 2 weeks ago. I just used Powershell to turn it off again. Microsoft, STOP forcing me to change even when you say I won't have to change until 2020. I have specifically, intentionally changed a setting, it is absolutely unacceptable for you to change it back. This is not your account, it is mine. If you say I can still have clutter until 2020, then let me keep it without changing it around every couple weeks or just because I reinstall Outlook or whatever happened to reset it this time.
Side note, STOP telling me I should switch to Edge. I use Edge. I also use IE, I also use Chrome. I am an IT professional who has reasons for opening many different browsers for many different reasons. Constantly badgering me about something I've already been using is ridiculous. I use EDGE frequently, so stop suggesting I use it!
