Features keep coming out for Teams in high speed these days. Just the other day my company Teams client was able to change the scenery for "together mode". If you turn on your together mode, you should be able to click a "change" button in the bottom left corner of the meeting window. For now you can select between a couple of presets provided by Microsoft. Please note the following important notes: Some backgrounds have participant limitations (but the number of active participants are listed in the image) When you change the background, everyone who uses the together mode will see the same image Presenters may change the images, attendees may not.
