Teams Gets Resizable Windows and More Pop-Out Panes

In January 2025, Microsoft will introduce resizable Teams windows for the Windows and Mac desktop clients. This is a fundamental change to the client experience that will affect how end users interact with Teams. In a nutshell, users can resize panes like the chat list or meeting stage to a minimum of 360 pixels, which isn't a lot. On the other hand, you can zoom a Teams window to 400%, which is definitely a lot.
