Microsoft appears to be working on new 3D icons for its Office suite. Reddit users have discovered the new icons in an email survey from Microsoft, reports Windows Central .

Crowded trains, lunch and coffee lines: More people are working from the office. With office mandates taking effect and more to come, many workers are headed back whether they like it or not.
