Using Classic Outlook on Windows for personal email, calendar, and contact management
I'm running 15.20.8272.0 and the 'bug' is apparently still somewhere swimming around.
I have the options set exactly as shown in multiple posts.
Both classic and new Outlook are saddled with the MS button and I can't get it gone. Setting set with powershell (There's also a bug in the webgui there in the security portal FYI).
No dice.
