Using Classic Outlook on Windows for personal email, calendar, and contact management
It's not surprising that is takes so long for issues like this to be addressed, when the Microsoft Agent/ Moderator doesn't take the time to completely read the description of the problem and understand the issue. I would hope that this removal of the Previous and Next Item buttons ( as well as putting the Delete icon back in the more intuitive previous location) will get fixed in the near future, but I don't have a lot of confidence in that.
