Theme and Fluent icon updates in Teams on the web, Windows and Mac

When your users access Teams on the web, the default and dark themes will be updated as well as the icons for all themes. 

Microsoft uses the Fluent design system to ensure a cohesive and accessible design for all Microsoft products and users. Most changes are subtle, such as:

  • Added drop shadows between panels
  • Rounded corners for square graphical elements (like buttons)
  • Color adjustments to the default and dark themes

What you need to do to prepare

You might want to notify your users about this change.
