Using Classic Outlook on Windows for personal email, calendar, and contact management
I switched from Old to New think "Ooh new shiny stuff" .... Boy was I wrong, I was most definitely NOT shiny.
This feature is one of my most used and therefore, within 5 minutes, I was back on the old version.
C'Mon Microsoft, Get this sorted please - If you want people to migrate to your newer tools, at least make sure it has, at the very least, the same features.
