Apart from really wishing I could permanently disable this feature, I also think this is pretty useless, since most people in the meeting will tell you as soon as you start talking while muted often before the warning even appears. When you're not talking, they won't tell you, and therefore you would not want the warning to pop up.
The engineering team is continuing to work on adding support for multiple accounts on desktop clients. We will first launch support for 1 work/school account and 1 personal account so users can enjoy Teams for work and personal side-by-side. Windows and MacOS. Support for multiple work accounts is still being worked on and will come at a later date.
